Quote:Looks as if you used a ("protective?") filter on the lens. My guess is that one of the elements of the lens itself is flat enough to have the same effect, as I trust you did not use a filter on that 24mm.
I used a filter since it was a rental lens. Still this is the first time that I have seen such an emphasized effect.
Interestingly these ghostings aren't present in all images (of the bridge).
