I have D200, with very light use. Just all of the sudden started shooting over exposed shots...over by many stops not just a little. Went through camera reset to factory reset thinking maybe i had a setting off somewhere but problem remains, recharged the batts to full still over exposed. have discovered that when i use the in camera flash the pictures are exposed correctly. I got a book on D22-Field guide but hasn't helped. Anyone recognize this problem issue and can shed some light (no pun intended) I would greatly appreciate it. Jel
