The Year Of Full-Frame DSLRs

The landscape for nature photographers who are in the market for a full-frame DSLR has never been richer

6 fps
The Mark III also improves on the Mark II's drive rate, able to shoot those big files at 6 fps. That and the new AF system make the Mark III a much better wildlife and sports-action camera than its 3.9 fps predecessor.

63-Zone Metering
Improving on the 5D Mark II's 35-zone metering system, the Mark III's 63-zone iFCL (Focus, Color and Luminance) dual layer metering system (introduced in the EOS 7D) takes into consideration brightness, color and data from each of the AF system's 61 zones to provide good exposures in a wide range of shooting situations. As implemented in the 5D Mark III, it also offers center-weighted, partial (which reads the central 7.2% of the image area) and 1.5% spot metering.

HDR Mode
A new in-camera HDR mode merges three bracketed exposures into a single image with more detail from shadows through highlights. An automatic alignment function permits you to do HDRs handheld (although we'd recommend using a tripod).

Proven Battery
EOS 5D Mark II users moving up to the Mark III will be happy to note that the new camera uses the same LP-E6 Li-ion battery—and gets even more shots per charge. This battery also powers the EOS 7D and EOS 60D, good news for upgrading users of those cameras.

Durable Body
The 5D Mark III is more rugged than its predecessor and better sealed against weather. The sensor-cleaning system has also been improved. The shutter still carries a 150,000-cycle rating.

Video Features
The 5D Mark III offers two compression modes: IPB (for smaller files and thus more "footage" per memory card) and ALL-I (for easier editing). It can do 1920x1080 full HD at 30p and 24p (25p PAL), 1280x720 HD at 60p (50p PAL) and 640x480 SD at 30p (25p PAL), with adjustable mono sound via a built-in microphone or stereo via an optional external mic. There's also a headphone jack. You can use AF before you start to shoot, or focus manually, but there's no continuous AF while shooting video.

Dual Memory Card Slots
The 5D Mark III can save images on CompactFlash (UDMA-compatible) and SD/SDHC/SDXC cards, thanks to two card slots.
Lens Flexibility
The 5D Mark III can use all Canon EF and TS-E lenses for both still and video shooting—more than 60 lenses, from an 8-15mm fisheye zoom and a 14mm superwide-angle to an 800mm supertele, along with 1.4X and 2X teleconverters. (EF-S lenses designed for APS-C sensors can't be used.)
