Question about Pentax MZ-50 35mm SLR Camera
When the camera on/off switch is turned either on OR off, or when the batteries "chamber cover" is closed (with the on/off switch in either position), the film will advance one frame per action. The same will occur when the shutter release is half pressed, or when the Select Switch is moved either right or left, or when the Exposure Compensation button is pressed. The advance is reflected in the LCD panel indicating number of frames used and the motor can be heard. also the auto focus is heard. With the camera is turned off, none of the above occurs. When the film has been advanced to 24 frames, the film counter flashes 24 with the camera turned on OR off and will not advance past 24. At 24, the film will not rewind automatically. Opening the camera comfirms that the film has been winding on. On closing the camera the film counter flashes E with camera turned on or off. Using the mid roll rewind button will rewind the film and the flashing E will stop only after the rewound film has been removed. Re-inserting the rewound film will result in the flashing E appearing. The camera is loaded with a 24 frame film. The Mode dial is selected to PICT. The Mode Drive Switch is selected to single frame. Selectin AF or MF mode makes no difference. New batteries have been fitted and there is no battery low indication in the LCD panel. The batteries are fitted correctly. Owners maual offers no solution. Because of the above problem, the mid roll rewind button was used successfully and the film developed OK. Over to you
I have the exact same problem as you did. Did you find a fix for it?

Well, I'm not a camera repairman, but it sounds to me (and probably to you too) that the electronics are damaged or perhaps there's dust in the contacts inside. I also have an MZ-50. There's so many electronics involved and they don't age so gracefully. I would consider buying another one off eBay or you can get a ZX-30 (same as MZ-30) for $75 from Blue Moon Camera & Machine with a 1 year warranty (parts and labor). The best way would be, in my opinion, to get a manual, mechanical camera from the 1970s and put a good lens on it. Those seem to last forever. No electronics to worry about. Advance and rewind the film manually. You can use a digital camera as a light meter to set the aperture and shutter speed. I'm thinking of going this route when my MZ-50 finally conks out.
