My Pictograph AF seems to have a big problem. When switching it on,the AF display indicates "err", the bellows (I hope it's the right term) above the lens go up to the top as they should, but stay blocked there and the whole head, which is also motorized, can only go up and down on the column by small steps. When fiddling (nervously) with the buttons of the AF control panel it seems the number of the error is 165. I say "it seems" because, unlike other numbers which also appear (NV, PV values etc.) this number is the only one which cannot be changed when touching the + and - buttons. Anybody out there who can help me ?
