I just picked up very clean Mamiya M645 for 200 bucks. The seller said he could not get the camera to focus and the exposure meter did not work. I took it home and took out the Dioper lens and put the speed knob in the correct position. Now I just have to expose a roll and develope it. Some sellers just don't know what they have and some buyers don't know what they want to pay. I am glad I knew exactly what I wanted and what to look for. He originally wanted 300 for it. Yes I am happy
