Firmware update for the Canon EOS-1D X

Canon just released a firmware update for its flagship camera, the EOS-1D X. The firmware update addresses the following two issues, making this update a “must have” for most 1D X shooters:

• AF Point Illumination During AI Servo AF
• Cross-Type AF Support at f/8

You can download the firmware from the Canon USA website. Also be sure to download the revised instruction manual there as well.

Details for firmware 1.1.1

Firmware Version 1.1.1 incorporates the following improvements and fixes.

1. Enables the centre AF point to autofocus when the camera is used with lens/extender combinations whose combined maximum aperture is f/8 (f/5.6 without the firmware update).
   ^*Please see the “Lenses and Usable AF points” section of the revised instruction manual for more detail on the lens & camera combinations.
2. Displays the viewfinder information (such as the AF frames, grid, etc.) in red during autofocusing in AI Servo AF.
   ^*When shooting in dark environments during AI Servo AF, the AF points can be easily confirmed.
   ^*During AI Servo AF, the viewfinder will be lit intermittently, not continuously.
3. Corrects a phenomenon in which the metering value of the AE sensor becomes incorrect and the captured images become pitch-black depending on the timing of lens attachment and/or detachment.
4. Fixes a phenomenon in which Err 70 may occur during AEB shooting.
5. Corrects errors in the Arabic menu.
6. Fixes a phenomenon in which the firmware of the lenses cannot be updated normally./li>
