Firmware Update Version 1.0.7 and later improves and mitigates the following two types of image quality phenomena that occur under certain shooting conditions.
- "Black dot" phenomenon (the right side of point light sources become black)

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.
Note:
