EOS 5D Mark II, Canon is finally coming through with its long-promised 2.0.3 update that brings 29.97 FPS and 24 FPS (23.976, to be precise) 1080p recording at last. Even the VGA mode has been swapped to a 29.97 actual rate, and PAL mode has a flat 25 FPS and 23.976 FPS as well. Additional tweaks include a manual volume adjustment (as opposed to the automatic gain the cameras usually employ), a brightness or RGB histogram display (this function, like some of these other features, has been available for a while as a hack), shutter and aperture priority modes have been added for movie shooting, and the audio sampling ramp has been bumped from 44.1KHz to 48KHz. The bad news: now you don't have any excuses for not shooting that heartwrenching mumblecore masterpiece you've been telling everyone you're working on.
