Lens Problem?
Aug 8, 2014

Hi there

Can someone please help.

I got out my fantastic Canon SX40 after some time, and started taking pics. However, when on full zoom (and only on full or nearly full zoom) I get this horrible round blotch at the top of the picture (see pic)


. I have cleaned and cleaned the lens to as near perfection, but I can't get rid of it completely.

Does anyone know what causes this?
