Major Canon EOS 1D X Firmware Update Version 1.1.1 Now Available

1. Enables the center 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 details 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.

Wisely being asked over on the Facebook page is: Will the Canon EOS 5D Mark III, with essentially the same AF system, also get these features in a firmware update?
 
Again, B&H, Adorama and Amazon have the EOS 1D X in stock.
