    Can you give me a link to the circuit diagram, please? (For my repair man, if I decide to go that way)
    sure

    No, 300,000 is not a firm cut off number. The oldest cameras don't have gold plated switch wires. The OM-2 was undergoing constant upgrades during production. Your problem may be the manual shutter speed circuit under the main circuit. Clean carefully and lube LIGHTLY with a dielectric grease. John.

    John, I've been retired 10 years and memory's not great but wouldn't a simple mis-mesh of teeth cause these symptoms?
    If the OP has removed or loosened the lens mount that is?
    Just a thought...

    If I were in your situation, I would simply buy another body and get new seals installed. There are a lot of OM-2 cameras on the used market, and it probably isn't worth the time or money to invest more time and money having it repaired.

    I'm rapidly coming around to the same opinion: thanks!

    Mis-aligned shutter gear would cause gear to be off that amount at every setting. Circuit is designed so brushes are always in contact with one speed or the next, there is no space in between that would allow the shutter to stay open. If the problem has been diagnosed as showing in auto asa well then it's a whole different set of reasons. Could be oily magnet, dirty trigger, dirty non-gold switches at the back of the circuit board. Many things. John

    If buying another non-overhauled used body, you may end up with another 30 year old body with another set of problems. John

    A very good point, John (Oh why couldn't you be in Oz?)

    I think I'll just sit on it a bit, but thanks everyone for the input so far.

    However, it does seem the later models (e.g. OM2) may be a somewhat better bet due to the goldplating of the contacts, etc?

    I get repairs from Australia on a regular basis. John
