Firmware Update: EOS-1D X Mark II: Firmware Version 1.1.6

Firmware Version 1.1.6 incorporates the following fix:

  1. Fixes a phenomenon in which the camera may not function normally when images are simultaneously displayed on the camera’s LCD monitor and an external monitor (via HDMI output).

The Version 1.1.6 firmware being released at this time is for cameras with Firmware Version 1.1.4 or earlier. If the camera's firmware is already Version 1.1.6, it is not necessary to update the firmware.

When updating the firmware of your camera, please first go over the instructions thoroughly before you download the firmware.
The firmware update takes approximately six minutes.


  1. Once the EOS-1D X Mark II is updated to Version 1.1.2 (or later), it cannot be restored to a previous firmware version (Version 1.0.0 to 1.0.2).
  2. Camera settings files created using a camera running Firmware Version 1.0.2 (or earlier) cannot be used on a camera running Firmware Version 1.1.2 (or later).
  3. Please use the latest EOS Utility version with the EOS-1D X Mark II after the camera has been updated to Firmware Version 1.1.2 (or later). The latest version of EOS Utility can be downloaded from Canon’s Web site.
    EOS Utility Version 3.5.00 or later support cameras running Firmware Version 1.1.2 (or later)
  4. Accompanying functional improvements of Firmware Version 1.1.2 (or later), the instructional manual has been revised. The latest version of the instruction manual can be downloaded from Canon’s Web site, so please download the instruction manual together with the new firmware.
  5. When using Version 4.7.10 (or earlier) of Digital Photo Professional to edit JPEG/RAW images captured with a camera updated to Firmware Version 1.1.4 (or later), some of the Exif data may be deleted. In addition, chromatic aberration correction, peripheral illumination correction, distortion correction, and Digital Lens Optimizer cannot be used when processing RAW images captured using a TS-E lens (TS-E17mm F4L, TS-E24mm F3.5L II, TS-E50mm F2.8L Macro, TS-E90mm F2.8L Macro, or TS-E135mm F4L Macro). Please be sure to update Digital Photo Professional to Version 4.7.20 (or later) before performing image processing.
