Originally posted by Sarkhan Hello everyone,
recently, I have recovered my grand dads camera. I decided to buy two rolls of bw film (ilford pan 100 and fomapan creative professional 200). When I was shooting I noticed a strange thing, the shutter was fired only on every second shot. It just did nothing in the other cases - the shutter did not have any "resistance". Also, only every second frame of the film were exposed, the rest was blank. The film was developed by renowned photolab, so the issue should not be caused by lab mistake.
The second roll was even better. Everything was blank with the exception of the last picture, but the shutter could have been fired at every try, unlike the first roll. I thought, that I had spooled the film unproperly, but that seems unlikely, the rewinding knob moved and the last frame of the film was ok.
Also, when I look into the camera (lens removed, back open) I can see the mirror move up and down and the opening and falling aperture.
Soo, I have no idea, what can be wrong with the camera, everything seems fine.
Thank you for advice and pardon my English.

Sorry, there was supposed to be shutter instead of aperture. Just the thing which opens and closes as you expose the picture, not sure about the proper name in English.
Hello Sarkhan,
As others have pointed out, the ME Super and similar cameras (MG) can suffer from this problem. You may find this article informative:

I had a similar problem with two cameras, one an ME Super, the other an MG.
With the ME Super I sent if off for servicing from Eric Hendrickson here in the US. His service made everything very sweet again.
With the MG, the shutter would fail intermittently to fire, as you described. Once it fired it would fire again successfuly without problems IF I did not leave the camera unused for more than a couple of days. However, after a couple of days the camera would go back to its faulty operating condition. After various experiments I fixed the problem, and VERY SIMPLY. I left the shutter cocked for about a week or so, without operating the camera during that period. Now the problem has disappeared completely. It seem that leaving the shutter cocked must somehow rectify things internally.
I hope this helps. It is certainly worth a try. Leaving the shutter cocked will not harm the camera in any way, according to a Pentax technician I spoke with.
