Thank you for using Canon products.
Firmware Version 2.0.7 incorporates the following functional improvements and fixes:
Firmware Version 2.0.7 is for cameras with Firmware Version 2.0.3 or earlier. If your camera's firmware is already Version 2.0.7, 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.
*1: EOS Utility version 2.14.10a or later (Supported OSes: Windows 8/ 7 / 7 SP1 / VistaSP2 / XP SP3, Mac OS X v10.9 / 10.8 / 10.7 / 10.6)
