This camera specifications Up until now, the 5D series has been a dynasty of slightly unlikely revolutionaries. The original EOS 5D of 2005 was the firstaffordable full frame SLR, and the camera that cemented the 24x36mm sensor as the format of choice for many professional applications at a time when many were questioning its continued relevance. The 5D Mark II was the first SLR capable of recording full HD video, a feature that revolutionized the market in a fashion that no one could possibly have envisaged at the time - least of all Canon. On the face of it, though, the latest model offers little that looks likely to make the same impact.
The 5D Mark III has a 22MP full frame sensor in a body thats based on the EOS 7D design, and with a 61-point AF system borrowed from the flagship EOS-1D X. From the glass-half-empty point of view, this could be seen as an unambitious update that trails disappointingly behind Nikons 36MP D800 which was announced around the same time. But for those whose glasses tend more towards the half-full, it might just turn out to be the camera that 5D Mark II owners always really wanted.
Indeed the 5D name itself is almost misleading; compared to its predecessor the Mark III is essentially a completely new model, with every major system upgraded and updated. In a way its better seen as a full-frame 7D, with that cameras control layout, extensive customizability and 63-zone metering sensor. But it also gains a raft of additional tweaks and improvements in response to customer feedback; these range from dual slots for CF and SD cards, through a locking exposure mode dial, to a large depth of field preview button thats repositioned for right-handed operation, and can be reprogrammed to access a number of other functions.
Read on to find out out how the 5D Mark III performs in our studio and real-life tests, how we liked its handling and operation and if it is the right camera for your requirements and type of photography.

Most of the key specs are substantially upgraded compared to the 5D Mark II. The new sensor, coupled with Canons latest DIGIC 5+ processor, offers a standard ISO range of 100 - 25, 600 thats expandable to 50 - 102, 800. An 8-channel sensor readout enables continuous shooting at 6 fps. The shutter is rated to 150, 000 cycles and has been refined for quieter operation; the Mark III also inherits thesilent shutter mode previously seen on the 1D-series. Viewfinder coverage is a full 100%, and the 1040k dot, 3: 2 aspect ratio 3.2 LCD screen has improved anti-reflection properties and a hardened glass cover to protect against scratching. And lets not forget that 61-point focus system from the 1DX - the first time Canon has put its top-spec AF sensor into a non-1-series camera since the film-era EOS 3.
