An update has been released for the Canon EOS 5D Mark III firmware. The new Canon Camera firmware update adds two highly useful features: a clean HDMI output option and cross-type AF at f/8.

The new “mirroring” feature via the HDMI output allows video to be displayed on the rear LCD screen with or without scene and camera information while also outputting a clean video signal to a monitor or external recorder. An external recorder not only enables a video signal devoid of compression artifacts, but also allows a choice of preferred edit-ready codec, the ability to shoot in a variety of frame rates and bit rates, and longer record time.

Combined with the heightened color correction capabilities as a result of the expanded color space, post-production workflows will be smoother and offer users greater control and quality. With external recorders it is also possible to use a variety of on-set monitoring solutions, which facilitate real-time viewing of EOS 5D Mark III video with the Rec. ITU-R BT. 709 color matrix. Additionally, it will now be possible to synchronize the start and stop of EOS 5D Mark III video capture with the start and stop of the external recorder.

The new Canon EOS 5D Mark III firmware allows cross-type autofocusing with the center AF point when the maximum aperture becomes as small as f/8, in the same way that the EOS-1D X does.

If AF point expansion is selected with an f/8 maximum aperture lens/extender combination, the four AF points surrounding the center point will act as AF Assist points. This option effectively expands the size of the AF detection area to enhance autofocus performance with subjects that appear small in the viewfinder and difficult to track, such as small animals and birds in flight. AF points above and below the center will be sensitive to vertical contrast, while points to the left and right will be sensitive to horizontal contrast.
