Please: read and follow the instructions carefully.


Firmware Version 2.0.3 incorporates five enhancements to the movie function and a fix to the manual sensor cleaning function of the EOS 5D Mark II camera.

1. Adds or changes the following movie frame rates.


1920×1080 : 30 fps (changed – actual 29.97 fps)
1920×1080 : 24 fps (added – actual 23.976 fps)
640×480 : 30 fps (changed – actual 29.97 fps)


1920×1080 : 25 fps (added – actual 25.0 fps)
1920×1080 : 24 fps (added – actual 23.976 fps)
640×480 : 25 fps (added – actual 25.0 fps)

2. Adds a function for manually adjusting the sound recording level (64 levels).

3. Adds a histogram display (brightness or RGB) for shooting movies in manual exposure.

4. Adds shutter-priority AE mode (Tv) and aperture-priority AE (Av) mode to the exposure modes for shooting movies.

5. Changes the audio sampling frequency from 44.1 KHz to 48 KHz.

6. Fixes a phenomenon where communication between the camera and the attached lens is sometimes interrupted after manual sensor cleaning. (This phenomenon only affects units with Firmware Version 1.2.4.)

Firmware Version 2.0.3 is for cameras with firmware up to version 1.2.4. If the camera’s firmware is already version 2.0.3, it is not necessary to update the firmware.

Movies captured using EOS 5D Mark II cameras with Firmware Version 1.1.0 to 1.2.4 can be played back on cameras updated with Firmware Version 2.0.3. However, if you try to play back movies captured with a camera with the new firmare on a camera with a previous firmare version, a message, Cannot play back image, appears on the camera’s LCD monitor.

That will give you an extra perspective, not officially nor widely known. There are still many things that remain behind curtains…

We still also keep our List of Fixes & Improvements.

Some features of the list are  included in this new firmware release (other are in the T2i/550D !) and others might come in future.

Time (and some other factors) will tell…
