Yes, the meter indicator is clearly visible in the viewfinder. The needle may overlay the subject area, but it does not obstruct it.2. I can't quite work out the light meter situation with the OM1n. Can you see the meter through the viewfinder? I don't need intricate measurements. I just want the meter to be more or less accurate.
The original batteries for the OM-1 are not available. There are some said to be compatible, but I haven't tried them. The main options are conversions (zuiko.com does great work) or adapters (fit original battery chamber and hold smaller button battery). Zuiko.com sells the adapters for $45. I've never used the adapters. I have the camera updated.3. Also, are batteries easily available? I get the impression that OM2 batteries are current and fairly easy to get, whereas OM1 batteries are not? I don't want to have get anything converted or adapted.
Mine spent many years being stuffed in school desks and then many more years in a college backpack, a belt pouch, a pocket when the coat was roomy enough. It never complained.4. However, I quite like the idea of the OM1 shutter being mechanical.
Anything else I whould be thiking about when making a choice? I am not a collector. I want to actually throw the camera in my bag/pocket and use it on a day-to-day basis.
