I just read some exciting news for 5D Mk II owners. Any of you that utilize the video feature have already discovered that shutter speed, ISO, and aperture is all set by the camera when in video mode. For anyone that uses manual on any camera whether still or video knows how valuable it is to choose how the camera performs.

From DpReview.com:
Canon has announced a firmware update for its EOS 5D Mark II digital SLR enabling manual exposure when shooting videos. With the updated version, users will be able to manually adjust the shutter speed, aperture and ISO settings in the video mode. The new firmware will be available for download on 2 June 2009 from Canon’s website.
