I posted a thread a while ago about the rangefinder sticking in my R3A. Cleaning the camera myself helped a little at first, but the problem has ultimately persisted. Beyond this, it sounds like something is loose in the camera, as I can hear it rattle around. The focusing rectangle is no longer located in the center of the viewing frame anymore as well, and it travels toward the top left corner of the frame as I focus away from infinity. I'm thinking this may be related to the loose part, but I don't really know. Does anyone have any insight to this? If it needs to be sent out for repair, what are some good places to try? Thanks in advance.
