The EOS 5D MarkII Firmware Update improves and mitigates the following image quality phenomena.

1. “Black dot” phenomenon (the right side of point light sources becomes black)

When shooting night scenes, the right side of point light sources (such as lights from building windows) may become black. The phenomenon may become visible if the images are enlarged to 100% or greater on a monitor or if extremely large prints of the images are made. This firmware improves and mitigates this phenomenon.

2. Vertical banding noise

If the recording format is set to sRAW1, vertical banding noise may become visible depending on the camera settings, subject, and background. The firmware improves and mitigates this phenomenon.

When updating to Firmware Version 1.0.7, please also update the Digital Photo Professional and Picture Style Editor software.
