    Olympus OM-10 problem?

    I just bought an Olympus OM-10 with f1.8 and everready case, all in beautiful condition, for $28.00. It seems to work well, shutter sounds good, no dust in the VF, seems to have barely been used. Still has the inspection stickers.

    But the ASA setting dial is really hard to change, difficult enough so that some users might find it impossible. Is this normal? Is there a fix that I can do?

    Thanks for any and all help.

    Do you remember to lift the ring before turning the dial?

    ASA area probably has had some liquid spilled on it. Dried coke or other soda will make knob act like it's been glued. John

    Of course it is NOT normal....

    I took one apart once. I recall it's a small fine metal brush rotating along a carbon coated potentiometer. I recall the piece was plastic and rotated around a stainless steel spindle. My GUESS is same as John's... some kind of gunk must have formed around that area. This area is accessible if you take the top part off the body but putting it together correctly is very challenging as I recall. I would only attempt it on a junk body or as a last resort. Unfortunate thing is, to get it fixed by a professional will cost many times over the cost of the body itself...
    Develop, stop, fix.... wait.... where's my film?

    Before I saw the light and began buying single digit bodies, I owned a few OM10s. The best of them had silky smooth wind on and a very easy to adjust ISO setting. Almost regret selling it now

    The "gunk" or dried soda is in the plastic knob assembly on the top cover, not inside in the circuit board. John

    I wonder if if some TV contact cleaner sprayed into the knob assembly with with the camera held upside down would do the job. I've used Radio Shack's product successfully on some rather expensive electronic gear in the past.

    A drop(small) of Hydrogen Peroxide will free it up too.
