I can't seem to get rid of some very annoying dark spots that are very noticeable under certain lighting conditions. I've taken a test shot of my monitor showing a white background and amped up the contrast and blackness to highlight the problem areas.
I've tried with both a dust blower first, which didn't help, and then some liquid afterwards with a microfiber cloth. I know the problem is the sensor because the same spots persist with different lenses on different backgrounds.
Is this sensor toast or is there still hope here?
If the sensor is toast then what might be the cause of these persistent black spots?
I guess this is one advantage of a DSLR over a system camera like this - the sensor is protected by a mirror, even when swapping lenses.
