The OM-1 is completely manual.
I believe you're mistaking it with OM-2. The only thing that battery operates in OM-1 is "matchstick" type light meter.
Its funny how many people say that, not sure why....maybe they never owned one.?
I stand corrected. I have an OM2n, which does offer aperture priority. Not sure why I thought the OM-1 had the same feature.

I wonder why people like the Olympus MJU II. I wouldn't even pick it up if I saw it in an estate sales.
Neither would I. Limited controls and I constantly see people looking for them because their previous one has failed.
