Re: Light spot in center of sensor

My canon sx40 at full zoom has that light spot in center if there is even a tiny bit of a fingerprint on the front lens. I mean so minor that you can’t even see it is on the lens with pretty good flashlight shining in it. Cleaning my sx40 front lens with a micro fiber cloth fixed it. I would try that if I saw that in another lens.
