Still no extra bracketing tho !
Canon has announced a firmware update that will add a series of features to the EOS 7D. In an unusual move for a camera that has been on the market for almost three years, Canon is performing the most comprehensive firmware upgrade we can remember. This includes 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 will also enable the use of the GP-E2 GPS module. It will be available from August 2012.
