I've got a Pentax ES II in mostly working condition, the light meter works and the times seem to be accurate, however the focus mirror likes to lock up on me, it will look up, and then if i cock and shoot again it will come back down. I've got fresh batteries in it so i dont think that is the issue. |

Make sure the foam that cushions the mirror (when it flips up) is not sticky.
Sometimes the old foam causes the mirror to stay in the up position. |

The mirror cushion is certainly the first thing to check.
If it's not the mirror cushion, this anecdote may help. I had a mirror-return issue on a Spotmatic and fixed it by polishing and lightly lubricating a mechanism in the base of the camera. Slight tarnishing on the surface of the metal had caused friction that intermittently prevented the mirror from completing its cycle.
If you find that your mirror cushion is working properly, let us know and I'll post a picture of the mechanism concerned. |

I had an identical problem, but only when I took my ESII out in cold weather. Somewhere on the web I found a reference to it (I think the originator was French) and he suggested that the solution was as simple as a drop of light oil on the spindle of a certain gear in the base of the camera. The gear in question is as far as I remember the largest diameter one there and is dark grey/black in colour on a silver shaft. With the ESII of course it's necessary to remove the circuit board to access the mechanics, but that's easy enough. A single drop of oil sorted my problem. |

The mirror foam is pretty much entirely deteriorated, and isn't really stick or anything. I tried cleaning off what was left of it and testing again but it didn't seem to have much affect, perhaps new foam there would help?
Dmh: Any sort of advice or pictures would be most appreciated, i'm a novice when it comes to repairing cameras but i'de really like to learn more.
Steve: Thanks, i actually took a look inside the bottom after reading Dmh's response and didn't see much mechanical so i will definitely try to get under the electronics there and take a better look. |
