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.
