While I do service most Mamiya cameras and lenses, I do not service the 645AF/AFD series of cameras. There are two main reasons why these are difficult to get serviced: 1.) there is no longer a source for parts and they are often needed when repairing this camera 2.) any calibrations, adjusting or testing require special Mamiya software and fixtures to connect to the camera. If you already have one of these cameras, I unfortunately can’t give you any recommendation for a repair shop. I can recommend that you be very careful if you are looking at purchasing a 645AF and would probably tell you not to.
