Canon has updated the download page of Firmware 2.0.3

You can read the original Canon statement here.

A copy of the updated text is below:


EOS 5D Mark II Firmware Update Version 2.0.3

Recently we have discovered a malfunction that occurs with Firmware Version 2.0.3, in which the manual recording levels for C1/C2/C3 are changed and the camera becomes unable to record audio if the power is turned off (or if Auto power off takes effect) after registering “Sound Recording: Manual” in the camera user settings.

We apologize very sincerely for the inconvenience, but we are going to stop making this firmware available for download. For customers who have already updated to the new firmware, when using the camera with the mode dial set to C1/C2/C3, please either set the sound recording settings to Auto.

We are currently preparing firmware that will correct this malfunction. As soon as those preparations have been completed, we will let you know on this Web site. In the meantime, we apologize for the inconvenience this represents, but please wait until the fixed firmware is ready.


We really thank Canon for taking fast actions on this regard, and also those active users who took the initiative to share and report it immediately.


This is our remaining big concern: Are there any additional issues?

We are receiving reports that seem to indicate that possibility. Some of them:

РWeird noises coming from the lens and/or Aperture changes in M mode while not in LIveView mode, without the user doing any change. Even using different lenses.

Could it be another kind of malfunction in the connection between camera and lens? In fact it is one of the functions that was also recoded.

– Inconsistent stuttering and/or dropped frames on 24p (in some cases or cameras)

– Are black dots appearing again? One reader has posted a comment with a video test.

If you experience any of these or other malfunction: please REPORT it to Canon soon. You can also post it here (but report it to Canon).

Contact Canon: Information is here.
