Found this thread after just experiencing a problem with my Hexar RF. While exposing a roll of B&W a few weeks ago (after a long period of non-use), the camera behaved very erratically; as I recall, display number in frame counter window jumped ahead - don't know if new number was displayed - then film rewound. When processed, lots of blank frames resulted. Inserted an old expired roll to test the camera. I fired several shots a day for several days; film counter advanced normally. Then today, after firing several frames, the frame counter in window reverted to zero, and the film rewound before end of the roll. I'm afraid I have an expensive paperweight. From what I've seen on the web, I don't believe they're repairable; parts supply is nonexistent I've read. Does anyone have any ideas or suggestion? Does anyone repair this camera? I'm reverting to my trusty M6 and Minolta SR T's. Thanks for any inputs.
