Canon have launched a firmware update for the Canon EOS 7D camera that fixes a number of minor problems including the vertical magenta-coloured banding that has been spotted on some still images.
Firmware Version 1.2.1 incorporates the following improvements and fixes.
1. Extends the timing at which the high temperature warning indicator is displayed and the timing of automatic shut down of the camera due to a rise in internal temperature during Live View or EOS Movie functions.
2. Optimizes program shift when the ISO setting of the camera is set to AUTO.
3. Corrects a misspelling in the French-language menu.
4. Corrects a phenomenon in which vertical magenta-colored banding appears in still images taken in movie-shooting mode.
(This only occurs when in Manual exposure mode and when the ISO speed is set to "H". Note that this phenomenon only affects units with Firmware Version 1.2.0)
Canon also point out in the announcement that this is for users who use version 1.2.0 or below and follow on to say those already on 1.2.1 need not get the download which is kind of obvious really!
Firmware available here along with instructions on how to install it safely.
