Firmware Version 1.2.1 is for cameras with firmware version 1.2.0 or earlier. If the camera’s firmware is already version 1.2.1, it is not necessary to update the firmware.

Notes:

  • Once the EOS 5D Mark III camera is updated to version 1.2.1, it cannot be restored to a previous firmware version (Version 1.0.7 through 1.1.3).
  • It is recommended that the latest application software*1 be used, once the EOS 5D Mark III is updated to the new firmware version 1.2.1 from older firmware (versions 1.0.7 through 1.1.3). Certain previous versions of these applications do not support functions which are added by the new firmware.
  • In order to use EOS Utility software with the updated EOS 5D Mark III, the EOS Utility software must be updated to the latest version.

When cameras, or images taken with cameras, have been updated to the new Firmware Version 1.2.1 (or 1.2.0), and are used with the old version application software, the following phenomena will occur.

EOS Utility

  • The “HDMI output” function, “HDMI output setting” or “HDMI output frame rate setting” cannot be registered to My Menu of the camera.
  • The lens aberration compensation data cannot be registered to the camera.

Digital Photo Professional

  • If the Lens Aberration Correction Window is chosen when working with a RAW image taken with a camera running Firmware Version 1.2.1 or 1.2.0, the adjustment window will automatically shut down and the adjustment (correction) cannot be made.
  • Due to the differences in the camera firmware versions, the following phenomena will occur.
    • RAW images taken with a Firmware Version 1.2.1 (or 1.2.0) camera cannot be processed on cameras with Firmware Version 1.1.3 or before.
    • When images taken with a camera running Firmware Version 1.2.1 (or 1.2.0), are read by a camera running Firmware Version 1.1.3 or older, Direct print is not possible.
