As promised, Canon’s 2.0.3 firmware update for the 5D Mark II has been released. It adds 24p, 25p, a pre-record video histogram, and allows you to turn off the audio auto-gain. There are a few other enhancements, but those are the big kahunas that everyone has been asking for. You can download a copy here. Be aware that users are reporting an audio recording bug when shooting in Custom image modes (C1, C2, C3). Apparently when shooting using a custom image mode, audio is not recorded. Even worse, the audio level meters show levels, but nothing is recorded. Yikes.

This is a major bummer, as so many users utilize the Custom presets to flatten their image. There are some workarounds described here, but I’d say the safe thing for now is to either wait for the fix (Canon has acknowledged the issue and promised a fix), or avoid using Custom image presets when not shooting sync sound.

Here is Canon’s official response to the audio bug reports:

“We have learned that some users of the Canon EOS 5D Mark II digital SLR camera are experiencing issues with Firmware Update Version 2.0.3. We are working on a new firmware update to address these phenomena, which will be available soon.”
