This firmware update (Version 1.2.5) incorporates the following fixes.

  1. Corrects a phenomenon in which a displayed image becomes pitch-black if it is zoomed in on during Live View shooting.
  2. Corrects a phenomenon in which “busy” may continue to appear on the camera if the USB cable is disconnected during USB communication.
  3. Changes the error indications that are displayed on the camera. The error indications are further clarified to make the causes of errors easier to identify, and so that adequate support can be provided to our customers.


Firmware Version 1.2.5 is for cameras with firmware up to Version 1.2.3. If the camera’s firmware Version 1.2.5 has already been installed, it is not necessary to update the firmware.Canon EOS 1DmkIII Firmware Update download page
