Canon Releases New 5D Mark II Firmware

A few days ago Canon released firmware version 2.0.4  for the Canon 5D Mark II.  This came a few days after they released 2.0.3 which had some issues around sound recording for video.

The key features of 2.0.4 are:

  • Adds or changes a number of movie frame rates
  • Adds a function for manually adjusting the sound recording level (64 levels).
  • Adds a histogram display (brightness or RGB) for shooting movies in manual exposure.
  • Adds shutter-priority AE mode (Tv) and aperture-priority AE (Av) mode to the exposure modes for shooting movies.
  • Changes the audio sampling frequency from 44.1 KHz to 48 KHz.
  • Fixes a phenomenon where communication between the camera and the attached lens is sometimes interrupted after manual sensor cleaning.

I upgraded my firmware in less than 5 minutes.  While most of the features are behind the scenes, the sound level adjustment is nice.
