Some users of the Canon EOS 5D Mark II digital SLR camera have identified two types of image quality phenomena that appear under certain shooting conditions.

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

2.       Vertical banding noise

Firmware Update Version 1.0.7 that improves and mitigates these phenomena is now available for download by clicking here.

When updating to version 1.0.7, please also update the Digital Photo Professional and Picture Style Editor software. For details, please read the Firmware Q&A section on the firmware download page.

Details of the phenomena and shooting conditions under which they are likely to occur are as follows (if the camera firmware version is version 1.0.6):

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 above on a monitor or, if large prints of the images are made.

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.

o   Vertical banding noise is not noticeable if the recording format is set to sRAW2.

o   Vertical banding noise does not occur if the recording format is set to RAW or JPEG.

o   Noise can be reduced if C.Fn II-3: Highlight tone priority is set to 0:Disable.
