Hi All, I'm having a spot (no pun intended) on some photo's. I can take 4 photo's of the same thing, and some are developing "spots" whilst others do not have the blemish. I have checked for marks on the lens (it only happens with the 14-140) and cannot find anything. It is pretty annoying as I'm on holiday and some photo's are being ruined by the marks. The example below shows one spot, other photo's may have 2 or 3 on the photo's. Any thoughts on what it might be would be greatly appreciated. thanks Old Picker, currently in San Francisco.
