Canon EOS 7D Firmware 1.2.1 Publisher's description
Canon EOS 7D Firmware 1.2.1
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.)
It is highly recommended to always use the most recent driver version available.
