Alpha - humm... i don't think so... I've bought the camera few months ago... used it really often tho. I'm inspecting the optics... and i've noted that the UV filter on the 70-200 i've used to shot the pic is very dirty... it has a lot of halos on it... it's new and i've never cleaned it... maybe it could be that... i haven't noticed this spot on the other pic i've taken.... dunno....
