Canon has 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
Details of the phenomena and shooting conditions under which they are likely to occur are as follows.
'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.
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.
Vertical banding noise is not noticeable if the recording format is set to sRAW2.
Vertical banding noise does not occur if the recording format is set to RAW or JPEG.
Noise can be reduced if C.Fn II-3: Highlight tone priority is set to 0: Disable.
