Thank you for using Canon products.

Firmware Version 2.0.8 incorporates the following functional improvements and fixes:

Fixes a phenomenon which occurs when the “Shutter button half-press” menu item, configured in “C.Fn5: Operation”>”Custom Controls Menu”, is set to metering start only; depending on when the shutter button is half-pressed, it may initiate AutoFocus.

Firmware Version 2.0.8 is for cameras with Firmware Version 2.0.7 or earlier. If your camera's firmware is already Version 2.0.8, it is not necessary to update the firmware. The firmware update takes approximately seven minutes.





  • Once the EOS-1D X camera is updated to Version 2.0.7, it cannot be restored to a previous firmware version (Versions 1.0.2 through 2.0.3).
  • Once the EOS-1D X camera is updated to firmware Version 2.0.7 from previous firmware version (Versions 1.0.2 through 1.2.4 and 2.0.3), it is recommended that the latest application software*1 be used. Certain previous versions of this application software do not support functions which are added by the new firmware. You can download the latest application software from our Web site.
