In another widely anticipated move, Canon has finally announced an update to the firmware for their extremely popular Canon EOS 5D Mark II SLR camera. This update is mainly aimed at the video users that have been very disappointed (and very vocal about it) with the video controls that were included with the original camera.

This update brings several updates and improvements to the video controls for the camera, including manual control over the audio input level, and several new recording formats as well:

NOTE – Firmware Version 2.0.3 was very quickly superseded by 2.04 which fixed a few bugs that were introduced in 2.0.3. The major changes in 2.0.4 are the same as in 2.0.3.

Firmware Version 2.0.4 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
   NTSC:
   1920×1080:30 fps (changed – actual 29.97fps)
   1920×1080:24 fps (added – actual 23.976 fps)
   640×480:30 fps (changed – actual 29.97fps)
   PAL:
   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.)

This is a huge step in the right direction toward my programmable camera idea… 

Check out the open source project to create new firmware for the Canon 5D Mark II, codenamed Magic Lantern.  This project is still in beta, and they seem to be focusing primarily on improving the video aspects of the camera, but it works!  And I want it for my 40D.  It sounds like Magic Lantern could be quite quickly ported over to the 50D since they use a similar operating system, but the 40D appears to be an ugly stepchild that is difficult to hack.  I’m might just have to upgrade to the 5D (or maybe to the 1D Mark IV that is rumored to be forthcoming in the fall).
