f91
Anyway had a real strange issue with my 7D today while doing some sightseeing in Kiama.
Seems all of a sudden it just set the f-stop to f91 on my 10-22mm and I couldn't change it back - so one pic was way over-exposed!. Reattaching the lens did not help. I had to switch my camera on and off to clear the issue so looks like a intercommunication issue between the camera + lens or just camera itself.
Anyone had this happen?
Good excuse to get a new camera although my finances bit stretched atm.
Just a harmless explorer. No need to waste taxes checking me
