We have learned that 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.
- “Black dot” phenomenon (the right side of point light sources becomes black)
- Vertical banding noise
We are currently investigating and analysing the causes, and examining measures to reduce or eliminate these phenomena by providing correction firmware.
Canon apologizes for any inconvenience caused and thanks photographers for their patience.
