Randall,

I suspect the camera is faulty and suggest you phone the UK service centre on 01782 743345.

We just bought a used Mamiya M645 Super. After shooting a couple of rolls of film, we put new film in the boxes, and were going out to shoot again, and after the first shot, the camera would no longer take pictures. When you depress the button, a small red dot with an + in the middle, starts blinking on the upper left hand side of the view finder.
what does this mean and how do we fix it. My wife and I both have read the book that came with the camera, and find no mention of it anywhere.
