Thanks a lots Brian!
I haven't bought the M8 yet. Serial number say it is made in 2007 and the camera Has made about 14000 auctions. Now I can check this out whith the hidden service menue and thats's great. This camera has still 1/8000 s remaning! Then probobly shutter has not been changes or? The price, about 1700$ they ask for, what about that? I only want to give him 1200-1300$. He tried to fool me and sell it as a M8"black dot". But it has the 8000s on the wheel and I told him thats a M8 and not a M8.2. He told me, I only said it has a black dot... But I belive he was the one who was cheated when he bought the camera. That is why I asking about the camera mabe I can se in the hidden menue if the camera has been to service in Germany, mabe there some kind of kodes what has been done?
