I have a Sony A200 with Sal-1800 lens and sh0006 lens hood (both came with the lens kit). I am having a problem when I take a photo zoomed out all the way with the lens hood on and the flash, there is a half moon effect on the bottom center of the photos. I do not know why this is. When the flash is off it is fine, and when I zoom in a little bit it is fine, and when I take off the lens hood all is fine. Is this a problem with the flash (not going up as high as other cameras)? a problem with the lens hood (get a flower lens hood)? Any advice on how to deal with this. I mean, I could just zoom in a little bit and be OK, but I want to know if this is a problem everywhere.
