Canon EOS-1D X Firmware Update

Canon today announced the release of the 1D X firmware version 1.0.6 which includes an important fix for AF Microadjustment.


We wouldn’t normally shout about camera firmware updates, but this one is very relevant to FoCal.  There has been a bug to do with how AF Microadjustment is applied to the internal memory of the 1D-X which has meant that under certain quite common situations the settings are not properly stored.  This new firmware should fix this problem, and we would recommend that everyone that uses FoCal with a 1D-X ensures they upgrade to this new firmware.

You can download the software from the Canon website here.

Firmware Version 1.0.6 incorporates the following fixes.

1. Fixes a phenomenon in which the AF Microadjustment cannot be correctly carried out.

2. Fixes a phenomenon such that when using the camera with combinations of certain lens*1) and extender*2), the images captured become back-focused.

*1) EF 70-200mm f/2.8L IS II USM or EF200mm f/2L IS USM
*2) Extender EF 1.4x III or Extender EF 2x III

3. Fixes a phenomenon in which, when the camera is powered on in very dark environments (including instances when the lens cap or the body cap is attached), an Error 80 appears on the camera.

4. Fixes the following phenomenon, where if two CF cards are inserted into the camera and the
“Standard” or “Auto switch card” setting is selected for the recording method [Record func+card/folder sel] and then one of the CF cards is removed and reinserted into the card slot. The card selected for recording and playing back images may be switched to the other CF Card.

5. Fixes a phenomenon in which the AF microadjustment value is not correctly displayed in the EXIF information of captured images.

6. Displays an “O” or “X” to indicate whether images have been successfully transferred through the FTP protocol when using the WFT-E6 Wireless File Transmitter.
