Canon has tipped us off to a new firmware update for the EOS-5D Mark II, mostly related to HD movie recording. This latest update, version 2.0.3, will add 24p video acquisition and also lowers the frame rate in 30p mode to 29.97 fps. You also get manual audio control, a higher sampling frequency, a live histogram, plus the ability to record movies in shutter and aperture priority modes. The firmware update will be available later this month.
