Canon EOS 6D 20.2 MP CMOS Digital SLR Camera

Canon EOS 6D 20.2 MP CMOS Digital SLR Camera with 3.0-Inch LCD
  • 20.2 MP Full-Frame CMOS Sensor, 14-bit A/D Conversion, 100-25600 ISO Range
  • 11 Point AF points, 63-zone Dual-Level Metering Sensor
  • Canon iMAGE GATEWAY to Share and Upload Photos Anyhwere on iOS or Android Devices with Free EOS Remote Application
  • Built-in GPS Receiver and Wi-Fi Transmitter
  • Memory Cards: SD/SDHS/SDXC, and Ultra High-Speed (UHS-I) cards

This camera has top-tier image quality in a polished, compact package well-suited to travel. Those upgrading from a 5D II or 7D may prefer the sharp response and focusing performance of the 5D III. Buyers without an investment in the Canon system may find Nikon's D600 a better value.

I've finally had enough of a hands-on with this camera to draw some conclusions about it. My main body is a 5D II and I've owned or used almost all of Canon's crop bodies.

HANDLING AND NEW FEATURES:

Build quality on first impression is similar to the 60D and 5D II. Solid enough, with a slightly narrower grip than most previous Canon bodies, those two inclusive, but still comfortable to my large hands. This body is petite for full-frame, about 10% smaller by volume than the 5D II and 15% under the 5D III. Weight is similarly svelte, below every 5D and the 7D, and about even with the 60D. The larger cameras will balance a bit better with heavy lenses; this 6D will be the preferable travel body by a small margin.

New relative to the 5D II are improved weather sealing and a much-appreciated mode dial lock. It's not clear how comprehensive the sealing is; I still wouldn't take it in the rain, and very few non-L Canon lenses are weatherproof. The LCD screen has a fatter aspect ratio and somewhat better contrast. As seems to be the new Canon norm, the 6D has mushy buttons that activate at some indeterminate point.

Novel, however, is the button layout. The top panel retains the 60D's configuration of four buttons, each with one function. The 5D series, 7D, and prior XXD models have three buttons with two functions per. You lose direct adjustment of flash exposure compensation and white balance, but frankly, most people will find this simplified layout preferable. I still forget which dial controls which function on my 5D II. The rear panel looks superficially like the 60D with the same right-hand bias, though the functionality has been shifted around. A mitigating factor is that, as on the 7D, 60D, and subsequent bodies, you can bind custom functions to many buttons. I didn't find it a major trial to adapt from the 5D II, but you'll definitely want to spend a few days with it before you have to work under pressure. Rebel owners will find the adjustment more significant.

This 6D has a single SD card slot. The 5D II uses CF, which is rapidly becoming the purview of only high-end bodies. CF is faster, harder to lose, and costs more. SD is fast enough for a body in this speed class. This is nonfactor unless you have a sizeable collection of the opposing format. The 5D III has a dual slot that can speed some workflows and provide media redundancy.

Like all Canon full-frame DSLRs, this body doesn't have a popup flash. I'm not lamenting the absence, it was a bone to casual shooters more than a serious tool. Max sync speed for most Canon bodies is around 1/200, so integrated flash only works for outdoor fill with narrow apertures. Indoors as a main light source, the tiny size and close proximity to the lens lead to red eyes and a flat, unflattering high-contrast look. A much preferable setup for any Canon DSLR pairs a 430EX or 580EX, ideally diffused or aimed to bounce off a nearby surface.

Shutter lag now rivals the 5D III and 40D-7D, a few ticks quicker than the 5D II and any of the Rebels. Mirror blackout time is a more significant improvement, though still not quite level with the 5D III. The 5D II has a similar continuous-shooting rate and a more sluggish feel. Of greater interest: like the 5D III, the 6D now has a 'silent' shooting mode that lowers the volume and pitch of the mirror clunk by half. Every wedding I've ever shot would have benefited from that.

The screen interface follows the mold of every Canon body since the 40D. It has a series of horizontal tabs with options. The major UI change is that instead of 9 tabs that also scroll vertically, you get 15 that don't. The advantage is that you can rapidly wheel through tabs and see everything there is to see without scrolling; the disadvantage is that it looks intimidating and there are multiple tab groups of the same icon. The 'Creative' modes show every tab. Some are hidden in Program and Auto modes. We've come full-circle since the original 5D, which had a handful of tabs and piles of scrolling.

A major new feature also common to the 5D III is a better implementation of Auto-ISO. It's often the case in changing light where you want to shoot a lens wide open for subject isolation, but with a fixed or minimum shutter speed so you won't risk motion or hand blur. On the 5D II, that was a no-go; Auto-ISO didn't work in Manual mode, and the minimum shutter chosen in the other modes was too low. This camera will do Auto-ISO in M between any lower and upper bound you choose. Or you can set a minimum shutter for Av or P mode. Wonderful and overdue, this.

Some other new features are worthy of note. They've added a single-axis level that's useful for landscapes and architecture. The GPS feature will tag images with a location and can also keep a constant breadcrumb position log (at significant cost to battery life) that you can layer on a map later. And they've added wireless networking, so you can control the camera by smartphone or laptop with a live video feed. I can do that with my 5D II, but it requires a cable or USB-wireless converter dongle. In theory, you can also upload to Facebook by way of a Canon bridge website, but I didn't test this.

AUTOFOCUS:

AF is a marginal improvement over the 5D II. Performance and customizability are somewhat better, but usability suffers.

First, context: unlike a phone, point-and-shoot, or mirrorless body, DSLRs don't use the image sensor ("contrast detect") to focus for still photography through the viewfinder. That means you don't get face detection or any sort of scene recognition at all. Instead, you've got a handful of 'AF points' in a diamond configuration. Each point covers a tiny area of the frame. If you let the camera choose the point, it'll pick whichever is sitting on a contrasting edge (i.e., a clear dark/light edge; anything that isn't a flat color). Maybe that'll be an eye. It could just as easily be a button. The first major habit to acquire with a DSLR is picking your own focus points. The easier that is, the faster you can accurately shoot.

On the 5D II, there's a joystick on the back to individually select any of the 9 AF points with a single click. The phase sensor has 6 invisible AF-assist points to help track motion. Minimum light to focus with the center cross-point is -0.5 EV; in my case, that translated to an exposure of 1/50, f/2, ISO 25600 with a 100/2. Very dim, but not impossible to see and not out of the ISO capacity of this body or certainly the 6D. Shooting by moonlight or dim exterior lighting could benefit from greater AF sensitivity.

The 6D excels in this area. The center point is rated to -3 EV, a full 2.5 stops below the 5D II and is, in theory, at least a stop under any other Canon DSLR. There's essentially no handheld exposure, even with an f/1.4 or f/1.2 lens, for which this camera won't catch focus. But it's missing the 5D II's joystick; you have to awkwardly shift your thumb further down to use a less precise 8-way rocker panel. If you choose not to bind AF to the shutter button, you'll wear out that digit in a hurry. Also, the system now has 11 AF points (with no additional coverage), so you can't directly select the two outer points anymore.

As to motion tracking, the 6D's AF diagram suggests it may also have 6 or 8 AF-assist points. The manual doesn't say, and if they exist, they're not selectable. Either way, the same rules from the 5D II apply: if you're tracking a high-contrast object centered in the viewfinder in decent light, it works well enough. All bets are off if you need to rely on the outer points. Likewise for using the outer points with wide-aperture lenses; they don't always hit. You'll want to take a lot of safety shots if focus is critical.

There are a few new custom functions to fine-tune AI Servo. As with the 5D II, the 6D supports AF microadjustment, though now with separate settings for the wide and long ends of zoom lenses. Also interesting is the ability to link the AF point with camera orientation; helpful if you're switching from portrait to landscape repeatedly.

To the extent it's possible to narrow a wide array of AF characteristics to a 10-point scale, here's how I'd subjectively rate Canon's various bodies:

Center point / Outer points / Motion tracking | Body

9 / 9 / 9 | 5D III

6 / 6 / 7 | 7D

6 / 5 / 5 | 40D/50D/60D/T3i/T4i

7 / 3 / 4 | 6D

6 / 3 / 4 | 5D II

6 / 3 / 3 | T2i

Some scenarios will show greater disparities than these numbers suggest. A 6D in very dim light may well catch focus where every other body on this list fails. Likewise, very fast or erratic objects may flummox every camera here but the 5D III. I've ranked the 5D III's center point higher because, while it can't match the 6D in moonlight, it has significantly higher accuracy and consistency with recent Canon lenses.

STILLS IMAGE QUALITY:

Excellent. Per-pixel sharpness is very high and superior to crop bodies-par for the course for a full-frame sensor near this pixel density. Dynamic range is similar to the 5D II and 5D III. Noise performance in raw is a third-stop better than the 5D III, one stop ahead of the 5D II, and a little over 2 stops past the T2i/T3i/60D/7D. I'd run this body to ISO 12,800 without much thought. Colors at low ISO are indistinguishable from any other Canon DSLR.

Shadow noise has improved over earlier bodies. A common shooting technique is to meter for highlights and raise the shadows in post to make darker details visible, the manual equivalent of Canon's 'Auto Lighting Optimizer'. Boosting the shadows with a 5D II eventually reveals banding patterns and a blue cast. The 5D III fixes the banding, but retains the color cast. The 6D doesn't have either. While Nikon still holds a narrow lead on this point, 6D files are cleaner than every other Canon body save the 1D X.

To get the most out of this DSLR, you'll want to shoot raw. Post-production creates the bulk of the appeal of many photographs (see, e.g., Instagram) and JPEG often doesn't have the requisite flexibility. Raw shooting also lets you defer decisions (e.g., white balance, sharpening, noise reduction, color, distortion, tone curves, and even exposure) that distract from catching whatever moment you're after.

If you're careful configuring the body and the stars align, you can get decent JPEG output and forego work in post, but I consider a fast computer and a photo management system like Adobe Lightroom to be less complements than necessities.

LENSES:

I want to segue into this section because it's entwined with image quality. Comparing full-frame and crop isn't quite apples to apples. It's much easier to find crop lenses with good edge performance. Canon's current full-frame DSLRs make hash of almost all the mid-range variable-aperture zooms they've released over the years. I was pleased with my 28-135/3.5-5.6 IS on my 40D. Very consistent sharpness across the frame, even wide open. On full-frame, the same lens falls down. Poor edge performance, lots of aberrations.

Expect to pay 30-100% more on glass to feed this camera relative to EF-S lenses. Full-frame L glass costs a mint, but most of the third-party wide to mid-focal lenses don't emphasize edge performance. I've used a 14/2.8, 17-40/4, 16-35/2.8 II, 24-105/4, 100/2, and 200/2.8 among others. The latter two are stellar across the frame, as is the Samyang ultrawide. The 24-105/4L, 17-40/4L, and 16-35/2.8L II are merely good. None perform that well in the corners at wide apertures. Older wide-angles like the 17-35/2.8 fare even worse.

What should your kit be? Some considerations:

* Primes are lighter, smaller, cheaper, often available in wider apertures, often optically better, and have less manufacturing variation. They're less convenient, less versatile, updated with new technologies (e.g., stabilization, better lens coatings, weight reductions, faster or more accurate AF) less often, and can cause you to miss shots in fast-paced shooting environments.

* There are different requirements for movie lenses and still lenses. No Canon full-frame zooms are optimal for movies. Some are more optimal than others (e.g., less focus breathing, more parfocal, less distortion, smoother operation, distance scale). Primes often fare better.

* An f/2.8 lens on this body is just fast enough for most indoor use without flash. You'll want a flash for anything slower. A flash can provide more even, pleasing pictures, at the expense of a bulkier, attention-attracting rig.

* Kits with more than three primary lenses can become unwieldy in use. Two are preferable. My walkaround kit is a 16-35/2.8 and a 100/2, or a 24-105/4 alone if I expect to shoot movies. Professional event shooters tend to rely on the 16-35/2.8, 24-70/2.8, 70-200/2.8, and faster primes like the 85/1.2 as necessary.

* Third-party lenses tend to have less upfront cost, better warranties, and more aggressive designs. AF and optical performance is often (but not always) inferior to OEM lenses, quality control is less consistent, and resale values are lower. Value varies by lens model. Some are better than the OEM equivalents (e.g., Tamron 70-300 VC). Some fill holes in the OEM lineup (e.g., Sigma 120-300/2.8 OS). And some are lesser substitutes, but still competitive (e.g., Sigma 70-200/2.8 OS, Tamron 70-200/2.8 VC). Third-party lenses that duplicate the OEM with similar performance may not always be preferable to used copies of the OEM model.

VIDEO:

Out of the box, 6D video has five characteristics: lovely depth-of-field-control with the right lenses, clipped colors, high contrast, about 720p worth of actual detail at the 1080p setting, and issues with aliasing and moiré common to most Canon DSLRs. Moiré (false coloring and an interference pattern on subjects with repeating fine detail) in particular is more noticeable than with the 5D II and well behind the 5D III.

There are a few improvements over the 5D II. Canon has added time code support for better synchronization of events in post and superior on-camera editing controls. We now have 720p/50 and 720p/60 to complement the 1080p/25 and 1080p/30 modes. The compression algorithm is better, as is noise performance, and there's a slightly superior (though still quite slow) contrast-detect focusing algorithm.

Unbelievably, Canon still hasn't included focusing aids for manual focus. It's very difficult to judge focus from the LCD screen without overshooting and undershooting. Professionals that have to focus on the fly use a magnifier that sits on top of the LCD or rely on focusing aids in Magic Lantern, a third-party piggyback firmware available for the 5D II (but not yet for the 6D). For that reason alone, video here remains very much a professional feature.

In terms of post-processing flexibility, Canon EOS video is like shooting JPEG, but worse because the H.264 video codec throws away even more unseen data. You have none of the lossless adjustability of raw, so it's pivotal to lower contrast to preserve detail in the highlights and shadows, dial back the colors to prevent clipping, and lower sharpening so you can add it back in post without causing nasty artifacts. You do that by setting the correct white balance in advance and by creating or downloading a custom tone curve with low contrast, color, and sharpening. The latter won't affect your stills if you shoot in raw, so you can cater it solely to video.

Camera shake is another issue. If you're going to shoot without a tripod or Steadicam rig, get a stabilized lens. In fact, just buy the 24-105/4L IS. No other lens has the combination of size, weight, edge performance, range, stabilization, consistent aperture, speed, and partial parfocal (holding focus through the zoom range) ability.

The next best choice might be something like the Tamron 24-70/2.8 VC or Canon's upcoming 24-70/4L IS. Anything over 50mm that isn't stabilized will challenge your ability to record smooth footage. You can fix that later by transcoding to an editable format and using the anti-shake facilities of Adobe Premiere, Sony Vegas, or Virtual Dub with Deshaker, but that's a pain and they all crop the frame. Start with stabilization from the outset and save yourself the bother.

Stabilized lenses cause a new problem: the IS system is audible on the audio track. It's obvious with the 70-200/4L IS, noticeable with the 24-105/4L IS, and a background hum with the 70-200/2.8L IS I/II. That's in addition to dial clicks, finger movement, and wind noise, which obscure what would be fairly mediocre sound quality in the best case. The 6D records CD-quality 48 KHz 16-bit stereo tracks; the fault is with the internal monaural mic and amplifier. The simplest, most portable solution is to attach an external battery-powered mic to the flash hotshoe. The two most popular are around $250 from Rode. Zoom's H1 stereo recorder is a cheaper, more versatile alternative that can also be camera-mounted.

ACCESSORIES:

For video, buy SD cards 32 GB or larger. My pair of 16 GB cards have been inadequate for even a one-day event. Choose SanDisk. I've never had a SanDisk card of any size fail, they maintain higher resale value than other brands, and they tend to write somewhat faster than competitors with the same speed rating.

Interface responsiveness isn't much affected by card speed. Faster cards have three advantages: they can shoot longer bursts at 4.5 FPS, clear the picture buffer more quickly, and fulfill Canon's write speed requirement of 20 MB/s to record video at the highest quality. Buffer depth is 17 raw files with a UHS-1 ('Ultra High Speed') SD and 14 with a conventional card. Buffer cycling times are much lower with UHS-1. In one-shot mode, this difference is invisible; very fast cards would only make sense if you were time-limited on card-to-computer transfers with a USB 3.0, SATA, or Firewire card reader.

If you buy protection filters for your lenses, try Hoya's "DMC PRO1 Clear Protector Digital" line. They have 99.5% light transmission and don't cause flare. Digital sensors filter UV natively, there's no reason to pay more for that feature. I've written reviews on the relevant Hoya product pages with more details and why you might (or might not) want a filter.

Third-party batteries are hit or miss. The 6D refuses to read the charge capacity of certain LP-E6 copies that worked without fault in earlier cameras. Recognition aside, even the highly-rated models have their share of duds. I had an STK battery fail two weeks after purchase. I've never had, and have rarely heard of, a Canon OEM battery failure. They also tend to retain more charge capacity for a longer period. Your call whether that's worth five times the price.

NIKON D600 VS 6D:

(+) Focus tracking

(+) Focuses with f/8 lenses vs. f/5.6 (e.g., f/5.6 lens + 1.4X TC)

(+) 24 vs 20 MP

(+) Shadow noise at low-ISO

(+) 5.5 vs 4.5 fps

(+) Dual-SD slots

(+) DX crop mode

(+) Headphone monitoring port

(+) Pop-up flash

(+) More physical controls

(+) Auto-ISO even better

(-) No GPS

(-) No Wifi

(-) Center-point focus in very low light

(-) Noise at high-ISO

(-) Live View mode more limited

(-) Larger, heavier

(-) Early copies were prone to accumulating sensor cruft

On balance, while the 6D is a fine evolution of two older bodies (the 5D II and the 60D), the D600 is a simply a tier above in specification. The two brands give and take on the system level; Canon has a better service department and an edge with telephoto zooms and tilt-shift. Nikon has the best wide-angle zoom available on any mount. Consider the cost of your likely kit before judging by body prices.

SHOULD YOU BUY A 6D?

* If you're new to DSLRs:

Yes, with caveats. DSLRs give you lens flexibility, subject isolation, better low-light performance, and potentially superior motion tracking. They're also bulky, expensive, a suboptimal design for video, and inconsistent in the point-and-shoot modes. Mirrorless designs are more compact, easier to use, and better for video, but not as capable for stills or movement. Prosumer single-lens cameras are smaller, much cheaper, and with jack-of-all-trades functionality that less demanding users may find preferable.

Relative to crop DSLRs, full-frame bodies like the 6D give you better low-light performance. They cost more, require larger and more expensive lenses, and tend to be somewhat less responsive to fast action outside of the top product tiers.

If you've settled on full-frame, the two chief competitors are Canon and Nikon. Canon is a bigger company with a wider, more modern, and more readily available lens line, but it also tends to have more rigid product segmentation that can leave lower camera bodies wanting for some features. If you can swing the cost, both companies produce products capable of almost any photographic endeavor.

Among Canon's full-frame line, the choice is between an old new-stock 5D II, 6D, and 5D III. The 5D III is a faster body with extras like dual card slots that professionals appreciate. It also has a dramatically superior AF system for motion tracking and automatic AF point selection. Given that f/2.8 full-frame zoom lenses start at over $1000, the 6D's $800 price advantage over the 5D III on sale isn't enormous in the larger scheme. Something to consider if your subjects move a lot. The 5D II is fine if discounted 20% relative to the 6D; at the same price, I'd take the 6D for the new sensor, silent shutter, and Auto-ISO.

* If you have a Canon Rebel DSLR before the T4i:

Yes, if you're willing to trade comparatively cheap and small EF-S lenses for stellar noise performance, a bright viewfinder, superior low-light focusing, and a rear control dial, among the 6D's other enhancements.

* If you have a Rebel T4i, 60D, or 7D:

Same as above, but you're also trading speed and motion tracking, and the 6D doesn't gain as much in usability. A 60D isn't far removed from this 6D in feel. The 7D is a league apart: a league of amphetamines. If you want speed, low noise, and even better AF tracking, the 5D III is your body.

* If you have a 5D II:

No, if you're shooting predominately raw. There's little functionality in the 6D that can't be added to the 5D II and the bodies are very similar in capability. The exception is very low-light shooting. Moonlight, street-shooting at night, or star trails that benefit from locking onto a faint point source to set infinity will all be easier on a 6D, and the extra noise performance doesn't hurt. You're likely to miss the 5D II's AF joystick.

IN SUM:

I like this camera body. Stills image quality is extraordinary, and for that purpose, there's little to fault. Taken in isolation, the 6D is an enormously capable and polished photographic instrument, and $600 less than the 5D II was in 2008.

The quibbles appear when you consider it in the context of the larger market. It's an expensive camera with many of the same faults and limitations that were laboriously documented in the 5D II four years ago. The competition hasn't been resting on laurels; quality control aside, Nikon's D600 is more capable in many ways and often sells for less. I'd still choose Canon on the strength of the Canon system, but others may find greater value elsewhere.

If you intend to downvote, please leave a comment. I do try to be accurate, I'd much prefer to know the issue.

Buy Canon EOS 6D 20.2 MP CMOS Digital SLR Camera Now

Just received a 6D as a backup to my 5D Mark III. I am not going to bore you with the specifications that you can Google to find. I know most of you are reading this because you are getting into an entry level full frame camera or go straight to pro. Among your choices are Canon 6D, 5D Mark III and Nikon D600 which I will cover here. As for the D800, you can find lots of reviews online which I won't get into here. This review will be a side by side comparison of the actual photos.

ISO noise comparison

After spending the night taking several comparison photos at ISO 3200 F4 1/125, 6400 F4 1/500, 12800 F4 1/250 and 25600 F4 1/1000, here is my conclusion. Photoshop enlarged at 350% shows the 6D has about a one stop advantage over the 5D Mark III and 1-1/2 stop over the Nikon D600. That did not come as a surprise since the 6D has the lowest resolution among the 3 DSLR.

Update 12/7/2012: When these photos were reviewed in raw, I discovered the 6D filter setting is different, making it looked like it had lower noise. The 6D and 5D Mark III are in fact only about half stop better in ISO performance when compared in raw and one stop better than the Nikon D600.

Auto Focus

5D Mark III is the fastest, then D600 then 6D. There are all very close and hard to tell even when they are in dark condition. All 3 shows remarkable speed handling focus. 6D occasionally will hunt for split seconds. D600 and 5D both have no hesitation locking in especially the 5D. To test how fast each focuses, I listened to the motor sound of the lens until it stopped.

Auto White Balance

5D Mark III and 6D both have excellent auto white balance and the color under different lighting condition showed the true color. Nikon D600 however has a greenish or yellowish tone depending on the Kelvin, turning a red rose into orange under fluorescent light. This can be corrected of course under Lightroom but quite difficult adjust on the camera.

View Finder

5D Mark III has similar view finder as the 6D and both are brighter than the D600. This makes it a lot easier to focus especially in poor light. This is a big deal for my aging eyes and the brighter view finder is truly helpful on the Canon. I believe this is due to larger mirrors used in the Canons. The 6D does not have the 100% view but since I am not a pro, it really does not bother me.

Weight

The 6D is the lightest of the 3 cameras but the 6D does not feel cheap in the hands. There is lots of advange of being light especially I am going to use it on an Octocopter for aerial videos and photos.

Edge sharpness

6D clearly leads here. May be Canon has improved the image processing firmware here. 5D is not too far from the 6D but beats the D600.

Resolution

There is not much of a difference in the mega pixel of these camera, at least not enough to tell the difference even on a 24 inch monitor.

Video

Updates 2/24/2013

I have compared all 3 cameras extensively in video. Most of my videos were aerial shots from a Turbo Ace X88 octocopter under some air turbulence. So it will be a good test on their performance. First, I found there is no difference on the rolling shutter between the 3 cameras. The DSLR all still suffer this problem and this is where some of the cinema cameras such as the Red Scarlet/Epic shine. As for the moire and aliasing the Mark III is the clear winner. I barely notice any moire and aliasing on the roof tops and power lines. If you are going to do video on a more professional level which I am not, you should stick with the Mark III unless you invest on a Red or something surprisingly affordable like the Black Magic. As for the dynamic range, the D600 excels among the 3 cameras but by a narrow margin. The D600 has about 11.5 stops and the Mark III/6D are at 11 stops. The Red scarlet/Black Magic has 14 stops and shoots in 4K/2K which makes it more ideal than any DSLR for video. My only problem shooting video with the Red is flight time as it weights about 10 pounds with the gears. If my Octocopter struggles to keep it in the air, imaging what it is going to do to your arms. Now I am waiting on the new Turbo Ace CineWing 8 octocopter which will carries up to 25 pounds of payload with longer flight time, according to the specs so to speak. I should be able to achief 10-15 minutes flight time with Mark III and about half that for the Red Scarlet/Epic. It is exciting how these multi rotor copters give me room to creat and allow me to view the world in a different perspective. I will keep you updated on the aerial photo/cinematography technology with some breath taking aerial photos/video.

Updates 12/12/2012

To see the latest review, go to Youtube and search for "Canon 6D vs Nikon D600 vs 5D Mark III Hands-On"

Go to

To be honest I am quite impressed by the 6D and so far it's a keeper.

I have kept a record of the 12 photos with 4 different ISO settings for each of the 3 cameras which I will include in my comprehensive upcoming Youtube review.

Updates 12/4/2012: Moire is still best on the Mark III. No DSLR so far comes even close and that includes the 6D. The D600 suffers the same moire syndrome as the other DSLRs. That is disappointing as I was going to shoot lots of video with my Octocopter since it is so light and easy to handle in the air.

Between the Canons and Nikons, I've got say I am quite fond of the Nikon D600, I missed the built-in flash on both Canons. The D600 truly shines here as it is inconvenient to lug around a full size flash with my Canons. Canon thinks the build-in flash is not for a pro level camera, they are so wrong. I use the D600 flash mostly for fill-ins or trigger.

Updates 12/7/2012: My humble view of the dual SD card slots is that it is over hipped. Personally, I only use one slot in my Mark III unless I absolutely have to have backup in critical shoots in which case I would carry 2 cameras. The dual cards are confusing unless you are totally organized. Example: on the Mark III if you remove the SD which is in slot#2 and re-insert it back, the camera is set back to default slot#1 which is my CF. So the next photo I take, even though my original setting was on slot#2 is set back to slot#1 by the camera. This is a bug in the Mark III. When using dual cards, if your habit is to leave everything in the card for days and not download them to the computer frequently, you will not remember which photos are in which card and which ones are duplicate backups. Also remember, the dual slot does not work under video mode. Many here may be more organized and more diligent downloading your photos and will prefer this feature. To me a second camera as a backup is much better than a backup card, unless you wish to give the photos to your friends or customers.

Infrared sensor. On the 6D and Mark III, the infrared sensor is in front between the grip and the lens which can be blocked if the remote is more than 45 degrees from the camera. It does work quite well taking photos of yourself or using a remote trigger directly in front of the camera. The sensor on the D600 is located behind the camera. It makes it almost impossible to sense remote in front of the camera but it is very convenient if you are behind. It is a great camera for shooting candid photos of animals or if you are using a remote shutter trigger behind the camera. IMHO, the camera design should have 2 sensors, one in the back and one in the front. You have to do a lot of remote shutter shots to appreciate this.

Dynamic range. The D600 is about half a stop better in dynamic range than the Mark III and 6D. However it isn't quite noticeable until you pixel peep. The 6D is sharper, I believe this may have something to do with the way the images are processed.

Grip size. The two Canons fit larger hands than the Nikon D600. I have a medium size hand and the Canon grip fits just right, the D600 grip is too small for the average hands. With a caliper I measured where you clamp the grip between your fingers and your palm and the Mark III is 33.2mm, 6D 31.5mm and D600 28.3mm.

The review is based on photos and videos taken with the same manual settings and similar lenses. I tried hard to cover the important points but there are always going to be things that you feel should be added. Please let me know before you vote "NO" and I will be happy to help anyway I can.

Canon 6d Review

I've now been using my 6d for a bit over a week and feel that I've handled it enough to write a comprehensive review. First, let me tell you that I upgraded from a Rebel T2i, which I absolutely loved. I'm by no means a pro, and I don't typically get paid for my work; but I would classify myself as a photo enthusiast. I travel a lot and size and weight were factors in my decision to go with the 6d. I also like to shoot with available light, which is why I wanted to go full frame for the high ISO performance. For some reason it says I purchased the body only, but I actually bought the kit.

Let me address some of the "cons" that people are complaining about right out of the gate. I'm going to assume that most people considering the 6d are like me looking to upgrade from a nice point and shoot style camera or a Rebel series or other APS-C style DSLR. Nearly everything that people are stating are "cons" I never had on my Rebel in the first place, so I don't miss these features. The AF system has gotten a lot of attention, but on my Rebel, I used the center point 90% of the time for focusing. The center point on the 6d is just amazing. It focuses in an almost completely dark room. Certainly it will be able to focus for any situation when you are going to shoot hand held. I will take the simplified control of 11 AF points and an absolutely fantastic center focus point over 61 points (caveat: I don't shoot sports or other fast moving objects so I wouldn't really benefit from the addition points for tracking a moving subject).

I rarely, if ever, shoot video so not having a headphone jack doesn't bother me in the slightest. Also, not having a built in flash is no big deal to me either. I'm going to assume that people looking at this price range for a camera have an external flash and understand the limitations of a built in flash. I never used the one on my Rebel anyway. Finally, not having two SD card slots doesn't seem like a big loss to me. While I think the redundancy of two slots might be nice, I've never had an SD card fail on me and perpetually back up my images anyway.

24-105mm f/4 Kit Lens:

Honestly this was probably what was holding me back the most about going full frame. I previously have been using the Canon EF-S 17-55mm f/2.8 IS and I have to say that better than 90% of my pictures taken with my T2i were shot using this lens. While the 17-55 doesn't have a red ring or L in its name, it defiantly can run with the L glass. I worried that going from a relatively fast 2.8 (EF-S lenses do not fit on the 6d) to an f/4 would be limiting, but I also didn't want to give up IS and the 24-70mm was out of my price range anyway. Let me say that given the higher ISO performance, I don't really miss the stop I lost going to an f/4 lens. I actually like having a bit more reach with the 24-105. I would defiantly have kept my 17-55 f/2.8 if I could have, but I also don't feel limited by the 24-105 f/4. In the future I plan to get the 16-35 f/2.8 for use alongside the 25-105 f/4. So in summary, if you are like me and hesitating about giving up your 17-55mm f/2.8 for the 24-105 f/4, don't worry the kit lens is fantastic and you won't regret going full frame for a second.

ISO Performance:

Let me sum it up in one word: amazing. I hate noisy pictures and I'd hesitate to shoot much above ISO 400 with my T2i. I have no problem shooting at 3200-6400 with the 6d. I took some shots basically in the dark at 25,600 and they were defiantly usable. Low light performance is just amazing. I can't comment on how it compares to other full frame cameras, but I do know there is just no comparison between APS-C sensors and this one.

Auto ISO on this camera is awesome. I never used Auto ISO on my T2i (as I said above I hate noisy images and didn't like the camera constantly trying to push up the ISO). The Auto ISO on this camera lets you set a minimum shutter speed (great for people, like myself, who rarely use a tripod). It brings the shutter down to (near) the minimum, and then starts to the boost the ISO. Additionally (like most SLR's) you can set the maximum and minimum Auto ISO speeds.

Autofocus:

I touched on this above, but for its limitations, I actually like the AF system. I shoot mostly still subjects in available light and absolutely love the center AF point and its ability to focus in near dark conditions. AF is fast and of the few hundred pictures I've taken so far, hasn't missed yet. I like the simplicity of the 11-point AF system. I find the 61-point system hard to navigate. Coming from a Rebel, the AF system is very similar so there was really no learning curve when going to the 6d.

Design & Button Layout:

The 6d is surprisingly small and light. It's honestly not much bigger than my T2i, and only slightly heavier. It defiantly doesn't feel cheap though. It feels rugged, well built, and substantial in your hand. It doesn't have the plastic feel that the Rebels do. It feels like a pro-level camera. Coming from a Rebel, I felt pretty at home with the button layout. A few things are in different places (e.g. the mode dial is on the other side to make room for the top LCD screen) but I was adjusted within a day or so. The mode dial lock is a cool little feature, but I can't say I ever had an issue with the mode dial moving itself on my Rebel.

The 8-way rocker is a bit annoying, but still a step above the four way buttons on the Rebel series. It's also nice to have the wheel on the back to adjust aperture (or shutter speed) in Manual mode, instead of having to press and hold a button and use the main dial on the T2i. The menu system feels well laid out and everything is pretty easy to find. Also having two custom spots on the mode dial is a nice addition (people seems to be complaining there are only 2 instead of 3, but let me say that 2 is much better than the zero I had before!). You can use the custom spots for pretty much anything (I have my set up for exposure bracketing and portraits). The ISO button location also takes a bit of getting used to when moving from a Rebel to the 6d, but the reassessed button and raised dot make it relatively easy to adjust quickly. Also you can customize a lot of the button assignments in the custom functions menu.

Battery life seems to be pretty good so far. As expected, using GPS and WiFi considerably shorten the life, but it's certainly still acceptable. A note about aftermarket batteries: they work, but the camera doesn't play nice with them. If you put in an aftermarket battery the camera warns you that it isn't a Canon battery and asks if you want to continue. It also doesn't know how much battery life is remaining. I'm hoping the aftermarket battery manufacturers will update their batteries soon (Wassabi indicated within a month or two they would be releasing an update).

WiFi & GPS:

I bought this camera not really thinking I would use either of these features very often, but let me say they are welcome additions. The WiFi is pretty simple to set up (if you've ever set up a router or even configured your smart phone to connect to WiFi then you shouldn't have any issues). In less than 20 minutes I tried out connecting to an iPad, Android phone, laptop, and even a uploading directly to Facebook without any issues at all (note that you have to connect to your laptop first to set up Facebook and you have to register with Canon). Transferring images wirelessly from the 6d to a laptop is surprisingly fast and easy. Also, viewing images on an iPad wirelessly is easy (**01/07/2013: Canon confirmed to me that no dedicated iPad app is being developed and you must use the iPhone app). I don't have much to say about GPS, other than it works. I stepped outside and it acquired a satellite signal pretty fast. You can view the geotagged information either in the provided Canon Maps application or in Adobe Lightroom. I think this will be really great when I am traveling. Note that the GPS stays on even when the camera is off (WiFi does not, however). You can turn off (or at least turn down the frequency) of the "bread crumb" feature (which tracks your location at set intervals to plot your path) to save some battery life.

**01/06/2013: The 6d only supports 2.4 GHz wireless bands, so if you are running a 5 GHz band router you won't be able to connect. Note most routers operating in the 5 GHz band also support 2.4 GHz so it may just be a matter of changing some setting on your router.

Advanced Shooting Modes:

HDR, white balance and exposure bracketing, and multiple exposure modes are all really great features. I love to shoot HDR and the camera does a pretty decent job of aligning and merging the images when shooting hand held. I do feel limited in that you can only take three exposures in HDR mode. I also find it a pain to have to turn off RAW mode in order to turn on HDR. I actually prefer the exposure bracketing. You can bracket up to seven shots in 1/3 EV steps (note that if you want to bracket more than the default three shots you have to change a setting in the custom functions menu).

The camera contains a lot of features for JPEG shooters (since I shoot mostly RAW I don't use these features often, but they seem nice to have for people who don't use post processing software). The camera will now do lens profile corrections (fixing distortion, brightness, vignette, etc.) for the lens that is attached. I always apply this to my photos using Lightroom and it's nice to have in-camera.

Summary:

In sum, the 6d is a fantastic camera. I don't at all feel hampered by the so called "limitations" pointed out in some of the reviews (lack of pop of flash, only 11 AF points, a single SD card slot, etc.). If you are upgrading from a Rebel you will love the improved center AF point, high ISO performance, speed, build quality, advanced shooting modes, and WiFi and GPS built in. I don't feel the need to compare this camera to Nikon's or Canon's other offering, because honestly this is a fantastic camera in its own right. I was already invested with several lenses in the Canon system, so Nikon was never really a consideration for me. The choice was really between the 6d and the 5d M3 and given the relatively large cost difference the 6d was the clear choice. Also if your considering the 5d M2, I think the benefit of five plus years of development has greatly benefited the 6d, and therefore would highly recommend the 6d over the 5d M2 for the sensor and new Digic 5+ processor.

Pros:

+Awesome low light / high ISO performance

+Great center AF point for very low light focusing

+WiFi and GPS built in provide awesome flexibility in shooting, especially for travelers

+Relatively light and small (for a full frame) without sacrificing solid construction

+Very bright and clear viewfinder (especially when compared to the Rebels)

+Digic 5+ processor provides great JPEG improvements and fast enough shooting speed

Cons:

-Kit lens is only f/4, and the 24-70 f/2.8 is pricey!

-HDR mode is slightly cumbersome to use and disappointing with its three shot exposure limitation

-Button layout takes a bit to adjust to

I upgraded from a Rebel T2i w/ 18-135. Here's are my thoughts after taking the camera out on a shoot last night with the 24-105mm L.

Ergonomics:

Coming from a T2i, one thing that was incredibly difficult to get used to was where the ISO button is located at. It's no longer an isolated button but now a part of a group of 5 other buttons. The buttons are laid out as AF -> Drive -> ISO -> Metering -> LCD light. On the 5D MK3, the buttons are Metering/White balance -> AF/Drive -> ISO/Exposure -> LCD Light. The reason this is important is because from an ergonomic perspective, it's normal to just shift your right index finger from the jog wheel straight down to the ISO button and it's the first button right there. On the Canon 6D, I have to move my finger down and shift it over. I'm getting used to it, but I can't count how many times I've tried to change my ISO and I kept hitting the Metering button and kept taking my eye out of the viewfinder to make sure I didn't change any metering values. Luckily, even if you hit the metering button, settings don't change until you move the jog wheel. So if you're looking through the viewfinder and you hit a button and ISO doesn't show up, then shift your finger left one button. I'm sure this will just take time getting used to.

The viewfinder is significantly brighter which was something I never appreciated until using the 6D.

In regards to the focal points, the number of focal points seems to make a larger impact on this full frame camera than it did on my crop body (which only had 9 AF points which seemed plenty on the T2i) That is, all 11 of the focal points are towards the center of the frame and on the full frame it seems like there's a lot of places left "open" with no focal points. In other words, it seems like the focal points only cover about 50% of the viewfinder coverage whereas on my crop body (with only 9) it felt like the focal points covered 75% of the viewfinder. Does this matter in the real world? I've not yet to run into any problems, and I suppose one could always use live view focus if for whatever reason one needed a much more precise focus than the 11 AF points.

The quality of the center AF point however is superb, and I was surprised I was able to get focus in some situations where my crop body failed in low light situations.

In regards to low light image quality, I hated using anything ISO 3200 or higher on my crop body. Pictures were usable but often image quality suffered in graininess and I wouldn't use them for anything professional and even ISO 1600 was borderline but acceptable on my T2i. On the 6D however, I am impressed with the images at ISO 6400, and so far pretty good results at ISO 12800 as well. This was actually one of the biggest driving factors in me upgrading from a crop to a full frame, and I can say that the 6D does not disappoint in this regard.

The in-camera HDR is pretty effective. I was surprised at how easy it was to take HDR images without a tripod and have them automatically stitch together and still come out looking good. I am of the mentality that there are certain photos that HDR absolutely adds to a picture, but other times it can distract. The fact that it's so easy to get an HDR picture without a tripod in the field is definitely a plus for me. Keep in mind though that the HDR function will only be available if you are shooting in JPEG mode, so if you're currently set in RAW you'll have to change that setting before setting up the in camera HDR. Once you're finished with any HDR shots, you'll also have to remember to put your camera back in RAW mode.

Another nice feature is that there are different raw sizes. RAW 20MP @ 5472x3648, RAW(M) 11MP @ 4104x2736) and RAW(S)5MP @ 2736x1824. Exactly what it sounds like, but something I wasn't used to seeing on my T2i which always shot in full-size RAW. So if I'm just going out not doing anything serious, it's nice to have the option of a smaller file size while still retaining the benefits of a RAW image. Then again, if I'm not doing anything serious, I would probably just use a cell phone camera. Therefore, neither a pro or a con.

In regards to the Wifi features, I will say that the remote EOS app (Android and iPhone) is a far better solution than an articulating screen. When doing self-portraits, it is nice to be able to frame the picture with your phone remotely (remote shooting feature). After my shoot last night, I connected my phone and stuck the camera in the bag as I walked to my car. It felt a lot nicer reviewing my pictures through my phone (and deleting the ones I didn't like) using a touch interface. This is not necessarily a pro or a con, but it was refreshing and I found it to be a better solution as I could zoom with two fingers, pan, etc. I can also see that having a tablet with a larger screen would be useful in reviewing photos in the field. One other thing to mention is that transferring RAW files is pretty slow wirelessly, and it's probably quicker to just pop out the card and stick it in than it is to turn on the wifi settings in camera and then connect through the app.

Overall, I'm very satisfied in the upgrade from a T2i to this 6D and I feel it was the correct choice over the 5D MK3 for the following reasons (in order from greatest to least benefit:

Slightly better ISO performance (1/2 stop from what I read) over the MK3 -This may simply be due to the lower resolution / MP count.

Slightly improved (-3EV) center focus (as opposed to the -2.5EV on the MK3)

~$900-$1000 dollar price difference

Wireless / Remote EOS app. (The MK3 supports this but at the cost of a $500 dollar add-on)

The MK3 would be a better choice because:

More focal points

Slightly higher resolution

Location of the ISO button (just my opinion)

Dual Card slots (although for me this has zero purpose.)

Faster FPS (also has zero purpose cause if I ever need to 'machine gun' my camera 4.5 FPS a second is still plenty fast on the 6D)

Update: Canon has released a statement saying that they will allow the center point of the 5Dmk3 to autofocus at F/8 with a firmware update in April of 2013. That opens up a lot of cheaper lens solutions (100-400L 4-5.6) to be used with a 1.4TC to have a max reach of 580mm while retaining autofocus at f/8. This may have been a bigger decision point had I had known about this before purchasing the 6D. However, to the 6D's support, you can swap out the standard focusing screen with an EF-S focusing screen for manual focus. There's also live view focusing, so it's not really a dealbreaker.

Update: 1/1/2013

Couple of additional thoughts as I've had this camera. The EOS Remote shooting app for Android and iOS is really a great thing to have on a camera. I just got back from vacation with family and friends and as soon as I took a family photo (some were of people who I didn't know) I was able to ask them for their phone or email address and immediately send it to them. Almost like a modern day Polaroid. I also was able to get impromptu shots of me with my friends by setting the camera on my camera bag and doing the framing with the three of us sitting in front of a fireplace.

I've also thought about the lack of dual card slots a bit more, and I think that if you're going to earn money off your camera it might be better to get the 5D MK3 just in case you happen to have a card failure while shooting a wedding or other one time events that you can't reshoot. It's nice to have the extra insurance, but that's about all it gives you. Granted, I doubt a card failure would happen during an important shoot, but it's possible and could prevent you from delivering a product. I think if you're team photographing that this camera supplements a 5dmk3 well, but I like the extra insurance of having backups *just* in case a card failure were to happen as a single shooter. Certainly not a deal breaker by any means, but just food for thought.

I guess my requirements in a camera are different than anyone else's but here goes. I have been a working pro for over 30 years and have always used the most basic cameras you could imagine, Hasselblad and 4x5 Toyo. Frankly, I don't give a rats rosy red rear end about WiFi, GPS, in camera video etc. They are beside the point as far as I'm concerned and usually are just things that keep the old Canon vs Nikon thing going. The only thing I care about is the quality of image coming out of the camera, and I thoroughly object to paying for a camera body that will be out of date in four years that cost more than I paid for my Hasselblad with three lenses. That said this camera body fits in very nicely with my needs. Who says it's a consumer or prosumer body? Are you kidding me? It's a camera and having the six thousand dollar body or the five hundred dollar body doesn't make you a pro; you do! Now that I have vented here's what I see. Image quality is as good as you will get from a digital camera at this time. The grain and crispness of the image on my 27" MAC monitor are excellent. The first time I used the camera it was amazing how quiet it is; very quiet. There are some things I don't like about the focusing system but that has been the case on every autofocus camera I've ever used. The camera will not get it right everytime, however it is very fast and quiet in focusing. I also have a 60D and use it a lot. The single feature that I see on the 60D that is absent on this body is the articulating screen, but not for the reason most people think. I do a lot of studio work and one thing I hate is for the client to ask is they can see the raw image, or they try to sneak around the back of the camera to see what's on the monitor. With the articulating screen I just turn it over and no image appears on the back of the camera. They just assume it's the way "professional" cameras work since their camera has a picture that pops up immediately after it's taken and the question never comes up. I like this camera a lot; really more than the inevitable comparison camera body; the 5DMkii. I rented a body for a week to see if I liked it. After doing nearly 1,000 images with it, this will be the camera body I get. Very good camera and unless you're going to abuse it I have a very hard time understanding why it is that there is such a kerfuffle about it having a polycarbonate body and not an all metal body. I don't know about you but if I have to use the camera in the middle of a rain storm or eastern New Mexico dust storm I put a rain coat on it. If I drop it I expect it not to work so to me the ruggedness, or lack of ruggedness is a silly argument. This body is definitely the most "bang for the buck" if you're in a Canon system. If you're in a Nikon system you have my deepest sympathies.

I didn't rush to make a review of this camera, as I wanted to really put it through it's paces first. I won't try to list every feature or go over every bullet point (the above description does a fine job), but instead try to go over a few things which make a big difference to me as a 5D Mark II owner. For some background, I bought an original 5D in 2007, a 5DII in 2008 and have been working with these bodies ever since then. I also have experience with all of the Canon 1-series up through the 1DIII and 1DsIII. I currently log about 60,000 photos per year with the 5D Mark IIs as a professional wedding and portrait photographer. I shoot almost exclusively with fast L prime lenses in my work.

So after a week of solid shooting with the camera, here are the areas which are of note relative to previous 5D bodies:

**AUTOFOCUS**

AF is the elephant in the room here so I'll address it first. Good news, we now have a focusing system worth of it's price point. The AF system here is identical to that in the 1Dx and is THE most sophisticated AF system EVER put in any Canon body. It is superior to that in the 1DV and all bodies before it.

I have tested the AF point in servo and one shot mode with my fastest lenses. Speed, accuracy, and consistency have been exceptional and better than anything I have used before. AF gets the job done with zero drama. NO focus jitter, NO frontfocus, NO backfocus, nothing but near-instant, dead accurate focusing with all of my lenses. Even with my Sigma 85/1.4 (which gives my 5DII bodies absolute fits) is 100% accurate with no jitter on the 5DIII. Center AF point and all peripheral AF points are all usable with fast primes. With the 5DII you just use the center AF point and hope for the best (with often mixed results). You could forget using the outer AF points with fast lenses on previous 5D bodies. That has all changed now.

Just to see how far I could push it, I took my most difficult to focus lens (24/1.4 II), put it on the 5DIII, and tried to focus on my black lab in my dimly lit apartment. At a distance of about 2 feet I would able to lock focus on the dog's eye with the far left AF point at F1.4, 1/40, ISO4000. Think about that. I was able to focus on a black eye on a black dog in a dimly lit apartment at F1.4. The 5DII would have hunted all day long trying to do this, even with it's center AF point.

I could sit here and write a book on how happy this performance makes me. For what I do, if this were the only upgrade from the 5D Mark II, it alone would be worth of the $3500 price tag. That said, there is more...

**BUILD QUALITY**

It's hard to put my finger on exactly what changed, but the 5DIII just feels more substantial. It feels like a chopped down 1-series instead of a buffed up 10 series. The contour of the body has changed to fit your hand better. The rubber is also a new compound which is much grippier than before. The 5DIII feels much better to hold and use than the previous 5D bodies.

**SCREEN**

I wasn't expecting a big improvement here, but the screen is drop dead gorgeous. The height is about the same, but it's wider than that in the 5DII and fits the aspect of horizontal images perfectly now. The screen itself has better coatings which allow you to see it easier outside. The contrast, viewing angle, color, and saturation have all improved noticeably. It has a very similar look to a high end smartphone screen. This is a substantial upgrade from the 5DII's screen.

**IMAGE QUALITY**

Image quality is better than the 5DII, but not substantially so. Let me explain.

The 5DIII now natively amplifies the sensor data to ISO 25,600 whereas the 5DII only natively went to ISO 6400. This means that for anything higher than ISO 6400, the 5DIII is better. In RAW you are looking at an improvement of about 1/2 to 3/4 of a stop at high ISO. At lower ISOs, the noise level is about the same.

JPEG quality has improved much more though. The JPEG engine in this camera is staggeringly good and a solid 2 stops better at controlling noise at high ISO than the 5DII. It strikes the best balance of detail and noise control of any camera on the market right now. Note though that default NR in JPEG mode is fairly strong and that you will generally attain a better "look" from your files with the "low" NR setting.

As an aside, the nasty cross-hatch banding present in the deep shadows of 5DII files is now gone with the Mark III. There is still mild vertical banding, but it's similar to the original 5D and only visible when pushed heavily (3 or more stops).

**METERING**

I don't have any hard data on this, but I'm fully convinced the metering of the 5DIII is better than that of the 5DII. I find myself correcting with exposure compensation MUCH less now with the new body than with the mark II. Shooting with the two side the newfound metering accuracy of the mark III is very obvious. I found the 5DII metering very similar to the original 5D. The new 5DIII is much improved here.

**SPEED AND STORAGE**

Camera startup and operation is near-instant. Shutter lag and mirror blackout is now faster than before and leads to a more instant, responsive feel while shooting. This, combined with the vastly improved AF make for a radically different experience from previous 5D bodies.

Dual memory card slots mean you can now either backup your data to a 2nd slot *OR* you can "span" cards. Spanning means that once one card is full it will automatically swtich to the second card. SUCH a nice feature. I can't tell you how many times my card has filled up at the most inopportune moments and shooting stopped. No more.

Shooting speed is either 3fps or 6fps and the buffer is about 18 frames deep in RAW only with a fast CF card. You can shoot almost indefinitely in JPEG mode without hitting the buffer. For RAW I would recommend a 60MB/s CF card to take full advantage of the CF slot speed. The SD slot is slower, but still capable of about 30MB/s write speed.

**COLOR**

The 5D Mark II had a slight magenta color cast. This was easily correctable in post processing and wasn't a huge deal most of the time. I now report that color cast is gone and that the 5DIII's color is much more neutral. Skin tones in general look better due to the more neutral tone.

Additionally I have found auto white balance to be improved over previous 5D models. I've noticed that while post processing I'm having to correct color less with the 5DIII files than the 5DII files. This is very exciting, as it will save me a fair amount of time in post processing. Per usual, all of the cameras struggle under tungsten lighting. However, AWB is able to get color surprisingly close with anything that contains natural lighting.

**MENUS**

I would strongly advise reading the manual because there are a lot of new settings and options which won't be familar to 5DII users. There are also a LOT of different ways to set up your AF system, so a little experimentation is needed. In general, the menu system is more complicated that before, but this also allows a much greater degree of customization of the camera. In that regard, the 5DIII is much closer to a 1-series than before. Take the time to learn it and set it up correctly.

**MISC**

You now have the option to one-click zoom to 100% at your AF point. This means you can instantly check focusing with one button push. This saves a lot of time and frustration while shooting. There is also a "silent" shutter mode which only makes about 1/2 the noise as the standard shutter. You can do one-shot or 3FPS in silent shutter mode. 6FPS continuous is only available with the standard shutter mode.

Another brand new feature that's exciting is the ability to re-map buttons on the camera to perform other functions. The options are very extensive. One in particular I'm excited about is the ability to toggle one-shot with AI-Servo by clicking the DOF preview button (which is now on the right hand side of the camera, in perfect reach of your middle or ring finger). If you are shooting a still subject in one-shot and they start to move, simply push the DOF preview button and you're instantly in AI Servo mode. There is no need to move your hand, or even look away from the viewfinder. When you are done, simply release the button and you're back in one-shot mode.

**CONCLUSION**

Canon finally woke up with the 5D Mark III. The completeness of this refresh is hard to overstate, as there is no part of this camera that was left untouched from the Mark II. The overall experience of using the camera has been transformed to an entirely different level. You will be faster, better, and more efficient with a 5D Mark III relative to its predecessors.

The improvements here will most cater to those who shoot in demanding environments which require high ISO and fast, accurate autofocus. Canon basically fixed most every complaint anyone ever had with the 5DII while maintaining the things which made the 5DII great (resolution, image quality, small body).

The price of this body is probably about $500 too high compared to its primary competition the $3000 Nikon D800, which is likely to annoy some people. Though individually they cater to different types of photographers and have different strengths over the other, overall these two cameras are comparable products. If you are starting from scratch or have minimal gear investment, the D800 is worth a hard look at. If you are heavily invested in one system or another, you would probably do best just to stick with your current brand. Both are fine cameras and you can't go wrong with either one.

I was able to pre-order and the Canon 5D Mark III arrived on March 29th. I had mixed feelings when the press release first came out with the specs on the new Mark III. Several features that were high on my wish list didn't make it into the camera, but when I started seeing some of the image samples, particularly in low light, I knew I wanted it anyway.

I'm currently an owner of the 5D Mk II and the 60D and my expectations were that the Mk III would inherit many of the superior handling features of the newer 60D. I am an enthusiast and not a professional photographer but I do make my living shooting product photography for online sales. For pleasure I shoot nature, architecture, and the occasional portraits. I'm also an avid fan of DSLR video and the fact that these cameras can literally capture Hollywood quality footage with few modifications is a big deal to me and a lot of people in the independent cinematography community.

The much anticipated release of the 5D Mark III was a bit of a letdown to me initially. One of the things I LOVE about the 60D is the articulating screen. The articulating screen is so handy to have and a joy to use in situations where the camera needs to be at an odd angle, such as low to the ground, high above your head or in tight quarters. The other indispensable use for the articulating screen is shooting self-portraits and videos of yourself. As a one-man act, you can't shoot a video and also be in it at the same time if you can't see the screen! So I really couldn't believe it when Canon came out with the specs on the Mark III -and NO articulating screen!? It's a feature that has been in the lower-grade 60D and T3i for over a year and a half already, and here we're paying three times the price of the 60D we don't get it? COME ON, Canon!

Canon's reason for not including an articulating screen to preserve weatherproofing. To remedy this I'm getting the Swivi 5.6" HDMI LCD Screen which is a giant 5" articulating LCD screen that even has FOCUS PEAKING (really cool). I guess I'm making lemonade out of the lemons in this situation. Another feature that didn't make it into this camera that has all the cinematographers grumbling is there is no clean HDMI output which would allow the uncompressed video footage to be captured on an external recorder. This feature would have made this a true high-end movie making machine to rival the $30,000 RED ONE and knock the socks off the Panasonic GH2 and even the AF100. For myself, not a deal breaker... but the Nikon D800 has this.

Probably the most vexing thing that did not make it onto my wish list is the elimination of the rolling shutter problem. It has been reduced a little, but it has by no means been eliminated, so the jello effect remains an issue and impossible to completely remove in post. And so far, there has been NO program that has been able to eliminate it entirely without creating additional artifacts (believe me, I've wasted untold hours trying them all). Rolling shutter has only been reduced by 20% or so and I won't be fully satisfied shooting video until we get the global shutter and eliminate this unprofessional looking artifact altogether.

Continuous autofocus during video? It's not even an option. The Panasonic GH1/GH2 have it, and do it well. And now the Nikon D800 can auto focus continuously during video recording too, and includes face detection to keep subjects in focus. The only option for autofocus with this camera whole shooting video is still the old way: press the AF-ON button, and you'll set a clunky, noisy, re-focus point. So don't think about replacing your camcorder yet. Shooting video with this camera remains a manual focus affair best handled with a rig and follow-focus setup... classically handled as a two-man operation.

Those are my three primary disappointments. Now the fun part: all the great things (and more) that DID make it into my wish list:

1. Live View focusing with half depress of shutter button. The Mk II had a really awkward way of focusing while in Live View mode. You had to depress the separate AF button on the BACK of the camera, then hold absolutely still while you moved your finger back to the shutter button, and then take the shot. The Mk III acts just like the 60D in that you half press the shutter to focus, just as it SHOULD, which is to say exactly like shooting with a viewfinder. And you no longer have to go into the menu and set Live View to Stills-Only in order to get Exposure Simulation: The Mark III has a handy dedicated movie/stills mode switch.

2. Better low-light performance. Nikon has been beating out Canon in high ISO performance since the D3, then the D3s, the D3x, and the D700. It's taken two product cycles for Canon to finally catch up. The Mk II was the low-light king when it came out, and still performs exceptionally well, but the Mk III takes it to a new level. My initial test shots show that ISO 12800 on the Mk III has about the same noise levels as ISO 6400 on the Mk II, but with better sharpness and improved color rendition. ISO 12800 is actually usable for high-quality work, whereas at ISO 25600 things start to fall apart--but still plenty good enough for smaller web images. These ISO settings will allow you to actually get the shot even at night in situations that were previously unthinkable. Most importantly, overall image quality in terms of dynamic range and the quality of the noise at high ISOs has been improved for both stills and video.

The claims were that ISO 25600 on this camera was going to be like ISO 6400 on the Mark II, a two stop improvement. The truth is that it's not. It's just about a one stop improvement, maybe slightly more, but that's still a significant achievement.

3. No megapixel escalation! I was relieved that Canon DIDN'T try to stuff 36 megapixels into the Mk III. They kept it roughly the same at 22mp. Way to go, Canon! It's been proven time and time again that more megapixels doesn't make for a sharper image, only larger file sizes. "More megapixels equals better image quality is what's known as "the megapixel myth" Cramming in more megapixels means a lower signal-to-noise ratio and less full well capacity for each photo site. At some point you don't get more detail with a higher pixel count; you just spread the detail around on more pixels. I hardly ever need 21mp as it is, and I am absolutely relieved not to be dealing with larger files because I often shoot RAW.

4. Exposure bracketing. The Mk II could only do 3 exposure bracket shots automatically; the Mk III can do up to 7. Bingo! But you have to go to page 316 in the manual under Custom Settings to read how. It's not even in the index and the main entry under Exposure Bracketing says it does 3 (the default) and doesn't even mention that it can do up to 7. There is also White Balance Bracketing (redundant if you shoot RAW), but unfortunately no focus bracketing (focus stacking). That would have thrilled me. (Focus bracketing/stacking function is available via the Unified Magic Lantern Firmware for the 550D/60D/600D/50D/500D.)

5. Chromatic aberration correction. A feature inherent to Nikon and Panasonic micro 4/3, it's about time Canon got it. But it's unclear whether RAW images processed with PhotoShop Adobe RAW already have this applied or not... and you have to load in lens profiles manually. I will have to experiment with this.

6. Improved White Balance settings. One of the major gripes I have with all cameras is the accuracy of the Auto White Balance. Sure AWB works fine outdoors in natural light, but in indoor light it's usually awful. Even the tungsten setting is rarely accurate. Invariably I've had to create custom white balance settings on all my cameras using a white card. But FINALLY, on the Mk III, not only is the tungsten setting accurate, even the Auto setting gives decent results indoors.

7. Electronic Level. The 60D has it on the LCD. The 5D Mk III now has it. But get this--the Mk III not only has a side-to-side level, it has a FRONT TO BACK level too! Great for architectural photography. And there's more--a grid overlay and electronic level in the VIEWFINDER. (Once again you must go into Custom settings to set a shortcut button to enable this.) This is way more than I was hoping for and Canon gets bonus points for this.

8. Quiet shutter. The shutter noise from "mirror slap" has been greatly reduced even in Standard mode, and there's a new "silent shooting mode" where you don't hear the mirror at all. This is something I've always wanted in an SLR, and was pleasantly surprised. I guess Canon WAS listening after all.

9. Auto ISO in manual mode. This is so cool. You can set the camera to M, set the exact shutter speed and f/stop that you want, and let Auto ISO choose the ISO for the correct exposure. Considering that this camera gives good results up to ISO 12800, this is a really great way to achieve the exact depth of field and stop motion effect that you want, and let the camera pick the right ISO. Couldn't do this in Mk II. Works with stills and video.

9. Full video exposure control. Speaking of videos, the ability to control exposure when shooting videos has been greatly improved. The Mk II was the camera that started the whole DSLR movie craze. I'm sure that Canon never imagined when they stuck this feature onto the Mk II as an add-on, that it would explode into the DSLR cinematography revolution that it has. But the Mk II was severely hampered by crude exposure control. Now, full manual control is available. Strangely though, only auto ISO is available in Av, Tv, and P. There are more shooting modes: 1080p at 24, 25, or 30 FPS and 720p mode now does 50 or 60 FPS, with two compression options,including an I-frame only compression for better quality suitable for grading.

A whole wave of enthusiasts use the Magic Lantern firmware patch that allows cinematographers to gain access to enhanced functionality like manual audio, zebras, focus assist tools, and more. The Mk III now handles a few of these functions naively such as manual audio (and a headphone jack), plus a video ISO range that goes to 12,800 with 25,600 as an option.

10. The 4GB video file size limitation. Finally, Canon has crossed the 4gb file size barrier and supports file spanning. Now clips can go as long as 30 minutes instead of 12. A big improvement, but come on... The Panasonic GH1 & GH2 have been able to shoot video with NO time limitation for years. Continuous shooting is a MUST HAVE for event videographers. Sorry, this wish-list item still doesn't make the full cut. Why do camera manufacturers hamstring this when it's obvious these cameras are capable of unlimited video recording? Thirty minute cutoff due to a European tax law... can someone fix this PLEASE?

There is much more... of course the completely overhauled complex AF system, primarily for action shooters, dual CF and SD card support, and in-camera HDR and other image combining effects...

Biggest annoyance: the AF point selection button no longer controls magnification in Live View and playback mode. This is a big pain when you want to use focus assist in Live View, because you can no longer just use your right thumb... you have to take your left hand from the lens to press the magnify button which is now on the left side of the LCD. I hate when they move a button from the perfect spot to one that is NOT ERGONOMIC. Workaround: You can assign Magnify to the `Set' button which is on the right (but not to the old button which would have been better).

So here's the big question: at list price of thirty-five hundred dollars, should you upgrade? My thoughts:

A. If you are primarily a through-the-viewfinder still photographer shooting in good light (outdoors and flash), it's rather hard to justify the extra cost. Many of us have barely scratched the surface of the creative possibilities of the Mk II, and in many ways this is not a major upgrade for traditional style, properly lit photography. This camera isn't going to make you a better photographer, though some of the new tools like the electronic level are quite handy.

B. Cinematographers: There's already a lot of carping and moaning in the video camps that this upgrade is a big disappointment. I think it's great for part-time video shooters like me, but it's missing a lot of features that the pros were hoping for. Of course if they want all those pro features they can buy the Canon C300 for $16,000. But current users locked into Magic Lantern are probably going to have to wait for Magic Lantern to catch up anyway. They've already got Magic Lantern for the T2i, T3i, 50D and 60D, so it's just a matter of time.

C. Low light / night photographers, action sports, theater and concert shooters, documentary videographers: This upgrade is a MUST! This camera sets a new benchmark for image quality in less than optimal light conditions. That one stop advantage, better color depth and dynamic range in existing light is important to these guys and gals. The image quality improvement in low light is very noticeable.

C. The rest of us. Many pros are going to want this model, if not now, eventually. The state-of-the art feature set is quite impressive; the handling improvement is modest. For hobbyists, the steep price may be difficult to justify. The Mk II is still a fantastic tool and unless you really need ISO 12800 this isn't going to give you significantly better images than you can already achieve with the marvelous Mk II.

My verdict: An enthusiastic Five Stars as a still photography camera; Four Stars overall due to the lack of three important features that have been available from Panasonic for several years already: articulating screen, continuous autofocus during video, and unlimited video recording time.

If you're on the fence about upgrading or even a first time buyer, I hope my review has been useful. Happy Shooting!

UPDATE 4-24-2012: Users have reported and Canon has confirmed that exposure value when shooting in extremely dark conditions may be affected slightly if the upper LCD backlight is turned on at the same time. People have been calling this a "light leak" issue but that is a misnomer. It's really a non-issue. See details in the comments section.

Some quick observations on the 5D3. Before I go further I should explain I'll be comparing vs. the 5D2 and second, if you need to know about video, I can't be of any help there.

Received camera body from Amazon on 3/23. Lots of new features (5D2 manual is 259 pages; 5D3 manual is 403 pages). For the work I do, I was looking for two improvements over the 5D2: Ability to bracket more than 3 shots and much lower noise. The first wish was granted. As you probably know, the 5D3 does 7 exposures. Nikons do 9, but 7 is almost always enough. Those who need more will probably have a Promote remote anyway. Noise? Well, the 5D3 images are cleaner but I wouldn't say dramatically so. With the default noise settings and long exp NR set on, I'd say it's 1 to 1.5 stops better than the 5D2. Now, with a little Noiseware or other NR, you can get very clean images at 12800 with very little loss of detail so I don't consider this a problem. I guess it was unrealistic to expect the 5D3 to match the very low noise of my D700 but it would have been nice.

It's true that nearly every feature on the 5D3 is an upgrade over the 5D2. Not all of these will result in better images but it's fair to say that the entire "feel" of the 5D3, the layout, viewfinder, displays are all nicer than the 5D2. The two things that may be game changers, IMO, are the shutter and the AF. If you haven't heard and felt the shutter on the 5D3, you're in for a treat. It isn't just quieter; there is much less kick from the mirror. Add the "silent" mode and, wow. I would not be surprised to see signs in the future that say "Please set your camera to silent mode". As for AF, I never had a problem with the AF on the 5D2 so I'm less impressed here. But if you shoot moving subjects, the 5D3 has it all--predictive, wrap around, sequential, selective. The manual devotes 45 pages to setting autofocus.

A small thing that I've been waiting for, a dual axis electronic level is wonderful. For some time, digital SLRs have had an "artificial horizon" that tells you if you are tilting the camera to the left or right. That's nice but in almost all imaging software, rotating an image takes just a second. What these left/right levelers don't tell you is if you are tipping the camera up or down which can be a real pain with a super wide lens. Well, problem solved with the 5D3.

The in-camera HDR is a mixed bag. Output is jpeg only and even at that, it takes awhile for the 5D3 to register the images. (This could be my cards which are Lexar UDMA 400x & Sandisk Extreme IV). Anyhow, it's a fun feature. This brings me to yet another interesting feature. Since the 5D3 has two cards (CF + SD) you can record different file types to each card. In other words, you could have a RAW-only card and a JPEG-only card. I haven't tried this but I presume this would mean that you could shoot everything RAW except in-camera HDRs which, being jpegs, would end up on the other card. I get requests for jpegs so now I can put them on one card while keeping an all-RAW card for myself. You can also have redundant cards for backup, sequential for extra capacity, etc. As with the autofocus options, the possibilities are endless!

So, to summarize. Pros: Better AF, 100% viewfinder with electronic grid (no more screens), better LCD, faster drive and processor, fabulous shutter/mirror, 7-stop bracketing, 2-axis level, somewhat lower noise and thus somewhat cleaner images vs. 5D2, two card slots, uses same batteries as 5D2. Cons: Still no built-in flash (yes, it's very handy), in-camera HDR so-so, mode knob still feels flimsy (and it locks now, so be careful). All in all, this is a very nice, refined camera and anybody trading up from a 5D2 will be happy. And if you do get a 5D3, the person getting your 5D2 will be happy as well.

Just a footnote. One thing that comes through loud and clear from these reviews is how very different people's needs are and how differently they use a camera. I can only explain how a product meets or fails to meet my needs. I would not dream of saying you do/don't need this feature or "read and decide" as if I was some sort of oracle. You know what is or is not important to you and how much you're willing to pay for it. The web has made everybody a professional and an expert but when it's your money, the only expert is you.

Want Canon EOS 5D Mark III 22.3 MP Full Frame CMOS Discount?

I recently sold my Canon 7D and saved up to get this camera. After hearing so much talk about how much better the D800 is and how the Mark III is not worth the money, I decided to give it a shot rather than be influenced by comments on the web by people who never shot with the camera. Upon first inspection after opening my kit I was impressed at how sturdy and professional the camera felt. I always felt the 7D was very tough and sturdy but the 5D takes it to another level. The grip is great and sticks to your hand. It also covers the batter compartment. The camera grip has a great indent for your hand and an excellent thumb rest. Overall ergonomics are fantastic and the camera has a slick look but is bigger than the 7D at every dimension. No confusing this with an entry or midlevel camera. It screams pro, even without a grip.

The settings were easy to navigate and the dials are all in familiar places for the most part. The new zoom requires an extra keypress but I found it better to use the wheel than the old zoom in/out buttons once you get used to it. The new rate button on the left side seemed a bit useless to me but I reprogrammed it to protect images. The LCD was big and bright and shows lots of crisp detail when zooming in. Also very usable for macro with it's quick focus zoom. The best LCD I have ever seen on a camera. The Viewfinder also big and bright. Huge improvement over what you see using a cropped sensor. This is one of the many reasons to go full frame.

Now onto using the camera. Coming from the 7D I enjoyed pretty good autofocus but the 5D Mark III dominates it in every way. It is super fast, accurate and locks on in really dim light. There are several action modes to select for the autofocus that react to the type of movement that you choose. Really groundbreaking stuff. I found nothing negative to say about it. I spent an afternoon shooting a kids party outdoors with the 24-105 f/4. The kids were running around like maniacs and I came away with many great in focus shots.

In the past when using Auto ISO in manual mode I was nervous when it went to 3200 because of noise. No such case with this camera. Indoor photos without a flash are no problem. Especially when you use a nice bright prime. I can shoot ISO 6400 all day and it will look like ISO 1600 on a 7D. I know most people dont shoot Jpeg but if you ever want some painless shots of your kids or family and dont want to mess around with too much post processing, this camera produces the finest jpegs you will find in a camera. Obviously raw files are sharper and I found the RAW files from the MKIII to be sharp and contrasty. Noise is well controlled though obviously noisier than the jpegs. Overall the image quality is excellent.

A new addition to the camera I thought was awesome was the silent mode shooting. It does reduce your frame rate to 3 FPS but what you get in return in this mode is virtually silent performance with much less shutter vibration. A really awesome and underrated feature. One of the many improvements people forget to mention about this camera.

I have to say there is something special to me about the 5D Mark III. It's a camera that I just have fun with. Its fast, easy to use, produces great results at perfect file sizes. Gives you various options for jpeg and RAW to meet your needs. I'm sorry I cannot review the video but I have not had a chance to test it in detail in order to provide one.

I know people constantly say that it's $500 more than the Nikon D800 but the truth is that it really isnt. In the end you will end up spending more on Nikon gear because it's just more expensive. Just an example.

D800 + 24-120 f/4 = $4,299

5D MKIII kit with 24-105 f/4 = $4,299

Nikon 24-70 f/2.8 = 1,899

Canon 24-70 f/2.8 = 1,375

add the grip, other lenses and a flash and you pay more than the Canon equivalents.

This was an upgrade from a Canon EOS 5D Mark II for me.

Auto-focus

* As most people know, the auto-focus on the 5D Mark II was a horrible weak spot -only the center point was a "cross point", so none of the other points were accurate enough for fast f/1.2 and f/1.4 lenses, and the focusing speed in general was just not great. Mark III has professional-level autofocus now, with a wide array of cross point locations (exact number varies depending on the lens you are using), and very fast focusing speed. What was a major down-side is now a major up-side.

Low Light

* As mentioned above, the autofocusing is improved, and the differences in low light are very noticeable.

* Canon also claims a major improvement in noise at high ISO's. Personally, I do see an improvement, but not a huge improvement.

Exposure Bracketing / HDR / Stacking

* The Mark II supported only 3 exposures with bracketing, the Mark III now supports 7 exposures -A huge improvement in the software for anyone doing HDR.

* The Mark III has in-camera HDR processing, which is nice (perhaps to get an idea how something looks, on the spot), but not something I'll actually use for final images (I'm sure the processing abilities of HDR software on my desktop is going to be better than in a battery powered camera).

* The Mark III supports in-camera image stacking, which can be used for a variety of creative and scientific effects -I haven't played with this yet, but this may be very useful for me.

SD Card

* Having a second slot, with the second one being SD is a very nice addition, you can now put an Eye-Fi in your second slot, save jpeg to the eye-fi, have photos show up on your iPad in realtime, and have the RAW's saved to a CF card. Great for both pros and hobbyists.

* You can have two 32GB cards, one CF, one SD, and store all of your pictures with two backups in case one card fails -great for pro's.

* The software actually interacts with an Eye-Fi, so you can see the status of what the card is doing, a huge improvement over the hack-ish CF->SD->Eye Fi support in the Mark II.

Silent mode

* Your wedding photographer can now take many photos of the exchange of vows without making it sound like a paparazzi session.

* It is perhaps quiet enough for you to even take a few shots in places where photography is generally frowned on

Burst mode

* 6FPS is a major improvement

Physical feel

* This is something that doesn't really fit on a spec sheet, but the Mark III generally feels much stiffer / heavier / "professional" than the Mark II -much closer to a "1" feel.

Megapixels

* This was of course a let-down to many (including me). I do a lot of landscape photos, and very little sports/clubs, etc ... For my photos, noise reduction can be handled with very long exposures, and low ISO (and other methods). That said, the camera was such a large improvement in every other way, I am still happy.

Learning Curve

* There are so many new features / modes, it will actually take some time and practice (and reading to fully utilize the new body), not a complaint -but I was not expecting this coming from a 5D Mark II

UPDATE: After a trip to hawaii and a few weeks of usage, my opinion has improved a lot, and I've changed it from 4 stars to 5. The lower noise enables handheld macro photography in lower light situations than possible before, and the intuitive improvements to software have really made some huge improvements. While there is a large improvement to the autofocus, but only a minor improvement to pixel count -the very large number of minor improvements in the software have made it to the point that I couldn't imagine going back to the 5D Mark II. Great job, canon!
