As Canon promised back in October, it has released a firmware update for the EOS 5D Mark III with significant benefits for both stills and video shooters. Firmware version 1.2.1 allows uncompressed 8-bit 4:2:2 video output with time code over the HDMI port. Uncompressed video can be output while the video feed is simultaneously displayed via the rear LCD panel and recorded to the camera's CF/SD cards. A 'mirroring' feature gives the option of displaying camera and shooting information overlays on the LCD while maintaining video-only output over HDMI.
Wildlife and nature photographers will be pleased to know that the firmware enables cross-type autofocus when working with a maximum aperture of F8, as is possible in the EOS-1D X. Using an F4 telephoto 'L' lens coupled with a 2x extender, for instance, you can autofocus using the center AF point with cross-type sensitivity. In addition, the surrounding four AF points can be used as focus assist points.
