Canon EOS 5D Mark III

Product summary


22.3 megapixel, DIGIC 5+ image processing systems, a beefed up ISO range for better performance in low light conditions and a respectable continuous shooting mode, Canon’s latest release is the EOS 5D Mark III. Successor to the very popular EOS 5D Mark II, Canon has packed in some obvious features and some not so obvious ones while they have beefed up the price by a fat 30%. For professional photographers looking to upgrade, the choice between the Canon 5D Mark III and the Nikon D 800/ 800E could be a difficult one to make. At the end it might just turn to the fact as to what kind of photography you do and whether you are a Canon or a Nikon fan.


The Canon 5D Mark III features a 22.3 megapixel full frame sensor compared to the 36 megapixel of the Nikon D800. What it means straightaway is that the Nikon retains a whole lot of information and detail of the frames compared to the Canon. In any shooting requirement, details can be a matter of great advantage. For studio shoots such as products or even fashion photography, the Nikon D800 has a definite edge over the Canon. It is possible to crop and or blow out a sector of the frame or even print it and still retain an amazing amount of detail. In a real world however 22.3 megapixel should be enough.


Canon has transposed the focusing system of the 1DX onto the 5D Mark III. There has been a kind of borrowing going on for both Canon and Nikon, trying to bring forward more of their professional DSLR features to their semi-professional bodies. Tid bits of improvements made by Canon since the launch of the last 5D (too bad they only a bit of megapixel to the new 5D) has all made it to the 5D Mark III. One of the biggest complaints that the EOS 5D Mark II had (and for that matter the original first generation 5D too) was its tiny 9 point circular AF system. For professional photographers shooting in outdoor and even in studio setup, the limited opportunity to lock on focus was frustrating. This has now been bumped up quite significantly with the 61 point AF system with 41 cross type focusing points. Focusing is faster and one can have a lot of fun with it. Compared to the Nikon D800 which has a 51 point auto-focusing system and 15 cross type focusing points the Canon seems better off.

ISO and low light performance

Canon has beefed up the ISO performance to a fantastic 102,400. What it means is the camera can shoot pictures in the toughest of low lighting conditions. Even when there are no direct light source, the EOS 5D Mark III can shoot impressive frames using only the ambient light. The frames that you get at 3200 are still usable. If you go higher, the noise becomes prominent and there are less and less chance of being able to use the shots that you shoot. Compared to the Nikon it has a better ISO range but poor performance with color noise creeping in to the mid tones. The Nikon D800 has a definite edge as its photos are sharper than the Canon. Canon tend to smoothen out the frames at higher ISO. However, even in low light conditions, the Canon manages to have an impressive auto focusing performance.

Continuous shooting speeds

Faster continuous shooting speeds is a major advantage when shooting, well, faster subjects; and that means sports photography, a playful dog or a child that won’t simply sit down and allow itself to be photographed. So one would need a decently better performing continuous shooting mode. While at 6 fps the Canon 5D Mark III isn’t quite the best in terms of continuous shooting speeds, but still its performance is respectable. What is impressive is that it can keep shooting for around 20 frames before finally stalling and even at that point it gives a good continuous shooting speeds. The Nikon on the other hand is slower at 4 fps and does not have a great buffer either.

Video mode

Video modes are one of Canon’s specialties in the full frame DSLR cameras. The Mark III shoots videos in 1920 x 1080 (full HD) at 30 fps / 25 fps / 24 fps. If you prefer however to see the world a bit slower than usual, you will however have to switch to 720p HD when you can shoot at higher frame rates of 60 and 50. The Nikon too shoots Full HD 1080p video at 30/25/24p with stereo sound. What the Canon has in addition to the option to plug in external earphone plugs (which the Nikon has too) is a volume level controller. This allows the Canon to control the volume levels whilst recording. The Nikon does not have this feature.

Recording media

Canon has introduced the dual card recording system in this camera. What it does is basically it allows you to use a SD card and a CF card simultaneously. You could either choose to record in one of them and then switch to the other seamlessly when the first one is full; or you could also choose to record the same images in exactly the same resolution in both the cards (come to think of it, professional wedding photographers will have a field day with this feature as they can now simply shoot and then hand over one card to their clients for review); or you could choose to record different quality images in different cards. Saves a lot of hassles really.

Weather sealing

Weather sealing is a major factor for some photographers, especially professional photographers worth their salt. The 5D Mark III comes with an all weather body. Handy that you can now shoot pictures with an utter disregard for the elements.

Final word

The Canon is more suitable for photojournalism while also being very good for studio photography. The impressive buffer and the fast continuous mode together with the 61 point AF system makes the Canon the choice for fast action photography among the two. The Nikon comparatively does not have nearly as good a buffer speed (to some extent the large 36 megapixel and file size makes it kind of slow to process which affects the final speeds) as the Canon. But the Nikon is definitely better for studio and really capturing a world of detail which is suitable for fashion photography and of course product photography. Also the Nikon has a better dynamic range compared to the Canon.
