Positioned between the existing Mark II and the upcoming high-end EOS-1D X, the Mark II is canon's highest resolution DSLR to date and comes with the 1D X's 61-Point High Density Reticular autofocus with 41 cross-types, a native ISO range from 100 to 25,600 (extended range: low 51,200 and 102,400), as well as video recording capability in 1080p at 24, 25, or 30 fps, or 720p at 50 or 60fps. Videos are encoded in H.264, feature audio level control with 64 levels and can have a maximum length of 29 minutes and 59 seconds.
At the core of the Mark III is the DIGIC 5+ imaging processor, which according to Canon is 17 times faster than the DIGIC 4. The chip enables nine new features the Mark II does not offer, including a burst shooting speed of 6 fps as well as HDR, in-camera RAW processing, a comparative playback function, two forms of movie compression, and support for high-speed UDMA 7 Compact Flash memory cards.
The new CMOS image sensor is promised to deliver higher sensitivity and lower noise levels for both RAW image data as well as in-camera JPEGs and movies compared to the 5D Mark II. Canon said that the camera delivers "outstanding image quality in all shooting conditions, even low light."
The camera will be available in retail this month for $3499 MSRP. A kit including the EF24-105mm f/4L IS USM zoom lens is priced at $4299. The new The Speedlite 600EX-RT flash with a wireless radio transmitter will be priced at $630.
