I recently joined this forum in anticipation of using a Mamiya pro 645 setup that I have recently purchased. Trouble is I can't get the dang thing to work! I have put new batteries in the body and winder, it seems to meter fine but the values in the viewfinder flash and the shutter won't fire. I have tried it with both the hand winder and power winder grip all to no avail. If I press the shutter release on the power winder it winds the whole film through without firing the shutter. I have removed the dark slide and set the camera settings to what the manual says to do. I have tried two different film backs and wasted several rolls of film and am now getting very frustrated (as well as getting low on film).
Is there something I have missed or have I bought a lemon? Please bare in mind that this is my first foray into medium format gear so it could be something very simple that I have missed.
