Body & Design

The 5D Mark III is very similar in size to its predecessor, but marks a distinct departure in layout from the previous models in the 5D line. It most closely resembles the EOS 7D, with its combined live view/movie control beside the viewfinder and power switch beneath the mode dial, but also borrows features from other recent Canon designs. So the 60D's mode dial lock reappears, along with the 1D X's little Q button between the joystick and rear dial. However there's further evolution of the EOS design that's entirely new to the 5D Mark III, including the repositioned depth of field preview button and revised playback controls.

The 5D Mark III's construction is excellent - it may not have quite the same level of disaster-proofing as the 1D X, but it certainly feels better-built and more substantial in your hand than the Mark II ever did. Perhaps the best way of describing this is that it's very much like the difference between the 50D and 7D - you wouldn't have said there was much wrong with the 50D in isolation, but the 7D is clearly better-built. The magnesium alloy shell certainly feels like it would come survive a pretty serious beating.

The top of the 5D Mark III resembles that of the EOS 7D, which means that the control set familiar to 5D Mark II owners is joined by an easily-reached customizable M-Fn button just behind the shutter release. The On/Off switch has migrated to a point where it's less easy to knock accidentally - but also less easy to reach when supporting a large lens with your left hand.

The 5D Mark III's top controls will look immediately familiar to existing Canon owners. Behind the shutter release is the main control dial - this changes the primary exposure parameter, e.g. aperture in Av mode. Between the two is the customizable M-Fn button that can be set to operate functions such as Flash Exposure Lock.

Behind this is a row of three buttons which each activate two functions, changed using the front and rear dials. From left to right there's metering / white balance, AF / drive modes, and ISO / flash exposure compensation. The latter button is especially well-placed for changing ISO with the camera to your eye. Beside these is a smaller button that illuminates the top-plate LCD.

On the other side of the pentaprism you'll find the power switch and mode dial. This has the familiar four exposure modes - Program, Aperture priority, Shutter Priority and Manual - plus Bulb shutter mode and three custom positions into which you can save camera settings for specific commonly-encountered scenarios. There's also the Auto+ mode previously seen on the EOS 600D that offers a range of results-orientated creative control - we can't imagine many 5D Mark III owners will use this much, but it does make the camera a bit more 'shareable' with non-experts.

At the bottom of the picture is the new image effects button that offers access to Picture Styles, multiple exposure mode and in-camera HDR. The latter is unusually well-designed - it saves all of the original files (not just the in-camera processed version), including RAWs. Unlike Canon's PowerShots, the 5D Mark III auto-aligns shots when processing, so you can shoot hand-held. There's also a range of processing 'looks' on offer, from 'Natural' through to, well, distinctly unnatural.

Rear Controls

The rest of the 5D Mark III's major shooting controls are on the back, arranged for operation by your thumb. The combined Live View / Movie mode button comes from the 7D - if you flick the lever to the Movie position the camera enters live view with a 16:9 preview, so you can compose in the correct aspect ratio. Pressing the button at its centre then initiates recording. With the lever in the Stills position (as shown), pressing the button enters Live View.

The Q button brings up an interactive controls screen while shooting, that allows you to change camera parameters that can't necessarily be accessed directly through external buttons. It also brings overlaid option menus in Live View and Playback modes, offering rapid access to features such as in-camera RAW conversion.

The rest of the buttons and dials will be familiar to Mark II owners. The large rear dial sets exposure compensation in P, Av and Tv modes, and changes the aperture in Manual. The AF area mode selection button at the top right of the camera acts in conjunction with the index finger dial at the front of the camera to change AF area mode. Both the AF-ON and AE/FE Lock buttons can be assigned to customized functions. The multi-controller joystick is used to move the AF point around the frame, either in concert with the button on the top right corner or, if you prefer, directly (via a menu setting). We think the latter makes much more sense for fluid shooting, and find it odd that this behavior is not enabled by default.

There are also three new buttons on the back of the 5D Mark III, including the mysteriously-marked 'Rate'. Here's an overview of what they do, from top to bottom:

During stills shooting, gives direct access to Picture Style, Multiple Exposures, and in-camera HDR.

In playback, enters side-by-side image comparison mode. Here you can compare composition and focus of two versions of the same shot, compare histograms for exposure, or check sharpness of different areas of the same image.
In playback, allows direct 'star' rating of images (1-5) in a format recognized by many image management programs, i.e., Adobe Photoshop Lightroom.

Can be reassigned to Protect/Deprotect images if you prefer.
Magnify button - replaces zoom in / zoom out controls on camera's shoulder. In play mode, hold down and spin a dial to enlarge/reduce image.

In live view, cycles through full screen, 5x, and 10x views.

I am new to the Canon brand and was considering a 5D3 or a 7D2. I need a camera that captures images and short video clips of very fast sports at close and far ranges. So for me, speed, image quality, and movie quality are the most important.

Edit: I should add that the sports are indoor but very fast, and I usually cannot use flash, so I have to work with what's available.

If there is another camera that you recommend beyond these two, please let me know. I have only used a Nikon D4S in the past which did well but I can no longer use that. Thanks in advance and sorry if this is a low-level question.

Hello, I've just bought a 5D3 W/ 24 - 105MM lens, upon playing w/ it, looking for the command for multiple shots, the auto focus was affected and not wokring anymore. I don't know and can not make it back to original setting. Is somebody there know and tell me what to do? please help.
P.S. I tried the lens to put in another camera and it works, and attached another lens to 5d3, but didn't work as well. so I confirmed that the problem is the setting w/in the body.


A minor nitpick: Canon's first 35mm autofocus SLR was not the EOS 650 but the T80.


Hello i just need a professional opinion....is the Canon 5D Mark III suitable for broadcast?

No one has answered, so here is an non-professional opinion: Should be. Since the Mark II, the 5D series has gotten some heavy use in broadcasting.


I have used the 5D Mark III for over a year and have just finished selling my Nikon gear (sad day after being a Nikon enthusiast for 30 plus years). From auto-focus to camera build to overall quality, this camera can do it all! Even with the slow burst rate, it works well for sports and nature shooting! I can't recommend this camera enough. I have found the auto-focus system to be quick enough for Equestrian events with long lenses, such as Canons 400mm f2.8 or new 200-560mm.


I have just bought a 5d mkii, and when doing a comparison test (nothing scientific) against my 50d I find that the 5d3 seems to under expose by upto 1stop, is this normal?


I work in Nyc as a fashion photographer and I have to say the the 5d series are the most used cameras out side of medium format cameras .Ive been shooting with the mark 3 for over a year after shooting with the mark 2 for 2 years great both great cameras. You can see the shots I've taken with it on my website www.brianschutzaphotography.com hope it helps!!

'Some people' buy Canon because they earn their living using a camera. Oh man, you should see those forests of white and red-ringed lenses in the pro pit at every major sporting, media and news event! 'Some people' are winning the major competitions, filling the fashion and nature magazines and filming box office busting movies with Canon. "Nikon has much sharper lens" Which lens exactly? Give a photographer a Canon 5D MKIII and an EF 70-200mm F/2.8 L IS II USM Lens and he can take on the world. Nikon is good, Canon is good why get tribal? it is so petty and amateur. At work I can pick up a Nikon/Sony D800 body or a Cannon 5D MKIII. I prefer the Cannon because I don't like the white balance on the Nikon. Others are happy to use the Nikon, but the die hard Nikon enthusiasts are disappointed that Sony make the sensors for Nikon. In comes Sony in comes the green tinged white balance.


No cameras white balance is perfectly neutral. That's why we have the ability to manually change it on the camera and even fine tune on some of the higher end models. Nikon cameras do run slightly toward the cool side, but they can always be fine-tuned to be neutral in-camera. Canon cameras have always leaned towards the orange color tint. Luckily for Canon the end result is a slightly warmer image that many photographers like the looks of. Few pros would buy a camera that couldn't be made to produce true colors. And that forest of white lenses has been thinning out quite a bit since the advent of the Nikon D3. I'm one die-hard Nikon enthusiast who's ecstatic with Sony sensors. No other brand can even match their dynamic range.

why is the D800 is the clear winner? because of a few test charts? which camera do you own? the 5DM3 or the D800? i switched from nikon to canon because i liked canon's lenses better.

ever been to a major sporting event or a press conference? if you did you'd notice an abundance of off-white telephoto lenses with red rings on them. saying that "some people buy Canon" is misleading because pretty much everyone who makes a living off their camera gear uses Canon. and believe me, there are very good reasons for that. if you don't know what they are then it will be a waste of time trying to explain them to you. you still wont get it because you are too busy looking at test charts.


The Nikon 85 1.2 and 200 1.8 is better than the Canon ones... oh wait, no, it was the 8-15 f4. ;)


thx for putting the Shadow noise test in your review. it was time to show that quite big difference.
