Canon EOS 5D Mark III review

Canon EOS 5D Mark III review - Design

While viewed from a distance it may appear that the 5D MkIII looks almost identical to its predecessor, there's been quite a few changes once you get them side-by-side and look a little closer. From the front, the newer model is a bit taller, while the pentaprism is more rounded and pronounced, making it look more like a 1D series DSLR without the built-in vertical grip.

Turn to the back of the camera, and the differences are more obvious. Here Canon has used the research it took out when developing the 7D and implemented with the 5D MkIII. The On/Off switch is now positioned round the collar of the mode dial, which now also has a button lock on it so it can't be knocked out of the desired mode inadvertently.

Where the On/Off used to be is now replaced by a lock switch for the rear dial, while there's also a dedicated Live View/Video switch positioned next to the viewfinder. You'll also find a Q button to gain access to a range of shooting functions, and over to the left of the screen, the column of buttons have also had their functions changed. Along with Delete and Playback buttons, you'll now find the Zoom button and Rate button - you can give images a star rating which will be recognized by image editing programs such as Lightroom, while above that is the new Creative Photo button, along with Menu and Info buttons.

While there's quite a bit changed from the 5D MkII, existing users should feel right at home, while also these alterations make for a more polished and refined interface.  

The body is constructed from high-grade magnesium, and there's now the same level of weather-sealing on the MkIII as there is on the 7D - a welcome improvement over the MkII, which was weak in this area. This means you should be able to carry on shooting with more confidence when the elements are against you.

All this means is that when you pick the 5D MkIII up, it instantly feels like a different class of camera to the 5D MkII. It feels much more durable and ready for business than its predecessor, and is more closely related to the 1D series. The handgrip is well proportioned, offering a comfortable grip, with the tactile feeling being enhanced by the high-quality textured grip.
