Up until now, the 5D series has been a dynasty of slightly unlikely revolutionaries. The original EOS 5D of 2005 was the first ‘affordable’ 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 that’s 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 Nikon’s 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 it’s better seen as a full-frame 7D, with that camera’s 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 that’s repositioned for right-handed operation, and can be reprogrammed to access a number of other functions.
Movie mode turned out to be the 5D Mark II’s trump card over its rivals, and its successor naturally offers improved capability in this regard. In terms of ergonomics, the camera gains the 7D’s rear movie mode/live view switch, so you no longer have to compromise your stills Live View settings when setting up for video recording. There’s a built-in headphone socket for audio monitoring, and rear control dial gains touch-sensitive ‘buttons’ that allow recording parameters (shutter speed, aperture, ISO and sound volume) to be changed silently. The video output specifications are essentially unchanged in terms of resolution and framerate (1080p30 maximum), but Canon says the processing is improved to minimise moiré and other artefacts, and has included the higher quality All-I and IPB interframe compression options introduced with the EOS-1D X. What you don’t get though, is the uncompressed output over HDMI seen in the latest Nikon models.
There’s a couple of entirely new features too; the 5D Mark III becomes Canon’s first SLR capable of in-camera High Dynamic Range shooting, in an unusually well-implemented and flexible fashion, and gets expanded autobracketing options too (up to 7 frames covering a vast +/- 8 EV range). It can also record multiple exposures, if you so desire. The introduction of DIGIC 5+ means that JPEG processing (finally) includes chromatic aberration correction, based on lens profiles which are stored in-camera (and therefore limited to Canon’s own lenses). Last but not least, playback mode adds the ability to compare images directly side-by-side, in a number of different views.
The 5D Mark III also gains a refreshed menu system, essentially based on that of the EOS-1D X. It’s not entirely dissimilar to the 5D Mark II’s (so existing users will still feel at home), but it gains a completely new tab for managing its complex AF system, based on a range of usage-scenario presets. The ordering of options has been rationalized, and a number of functions that were previously hidden deep within the custom functions have bubbled-up closer to the surface as top-level menu items, perhaps most notably mirror lockup and Highlight Tone Priority.
