    I made a post not too long ago about how I was only getting 10 shots out of my Mamiya 7 when using the Panoramic adapter and 36 frame 35mm film. Upon reflection however, I don't think the problem lies with the adapter at all, I think the camera isn't recognizing the increased length of the film. I've noticed on the back of the camera that when the film plate is rotated from 120 to 220/135 a small piece of metal is shifted over, and makes contact with another piece of metal in the camera body. I'm not sure if there is a mechanical problem with my Mamiya 7, everything else seems to work great. These have just been my observations, has anyone else ever experienced the same with their cameras?

    I should say that the reason I don't just pack the camera off to get repaired is the Kodachrome film I'd like to finish shooting before the deadline at the end of the year. The camera also doesn't seem to have any other issues, exhibiting good focus and exposure. I think I've found a workaround for now. When I finish the tenth frame, I can place the camera in my backpack (or other dark bag) and quickly open and close the back of the camera, resetting the film counter. Then, using the film re-winder that comes with the panoramic adapter, rewind the film exactly 5 turns to get back the film that will be advanced when the film counter moves from S to >>>1. I'll probably send it in to get looked at after the new year, but until then, if anyone has any thoughts, I'd love to hear them.
