Canon has released firmware version 2.0.0 for the EOS 7D. The update, originally announced in June, is the most comprehensive we can think of - significantly expanding the capabilities of the 7D. Changes include improved continuous-shooting buffer depth (to 25 Raws, up from the original 15), customizable Auto ISO, control of audio recording level for video and the ability to re-process Raws and rate images in-camera. The update also enables the use of the GP-E2 GPS module.
