CANON EOS 5D Mark III Firmware Version 1.2.1 Available

Canon EOS 5D Mark III users should be thrilled to learn that has just released exciting new free firmware. The highlight for nature photographers is that Canon has enabled centre AF point auto-focus when extender/lens combinations have combined maximum aperture of f/8. 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.
