Hi
I notice that when I take picture with small aperture, there is some black spots in the picture. I am able to duplicate it.
However, it will not be there with big aperture.
So can I conclude that it is actually the lense that is dirty and not the CCD sensor? Cos the CCD is behind the aperture which means that the aperture size should not affect it. Is this correct?
But what bothers me is that even when I change lense, it is still there.
i have cleaned my lense and do not see any dirt on it. Please advise if it is the lense or the CCD the is dirty.
