Well, would ya look at that. It’s been so long since they pre-announced it I’d almost forgotten Canon still owed all you 5D mark III shooters a new firmware, and at long last that fabled unicorn has burst majestically through the gates.
So, what does your patience land you today? According to the official change log, you get the following:
Firmware Version 1.2.1 incorporates the following functional improvements and fixes.
1. Uncompressed HDMI output is now enabled.
2. Enables the center AF point to autofocus when the camera is used with Canon EF lens/extender combinations whose combined maximum aperture is f/8.
3. Improves the speed of the camera’s acquisition of focus when using a Canon Speedlite’s AF-assist beam.
