Firmware version 1.0.6 for the EOS-1D X incorporates the following:
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 the EF 70-200mm f2.8L IS II USM or EF 200mm f2L IS USM and the Extender EF 1.4x III or Extender EF 2x III the images captured become back-focused;
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 a 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.
