5D Mark II Firmware Update

From Canon's Website:
Firmware Update Version 1.0.7 improves and mitigates the following two types of image quality phenomena that occur under certain shooting conditions.

1. "Black dot" phenomenon (the right side of point light sources become black)
2. Vertical banding noise

Firmware Version 1.0.7 is for EOS 5D Mark II cameras with firmware up to version 1.0.6. If the camera's firmware is already version 1.0.7, it is not necessary to update the firmware. When updating to Firmware Version 1.0.7, please also update the Digital Photo Professional (new version 3.5.2) and Picture Style Editor (new version 1.4.2) software.
