I love them, and their "ESP" metering, and have three (why, you ask...) - BUT they are unreliable battery-chewing dogs :-( with a "feature" that is apparently quite common: with the shutter completely locking up and refusing to budge - something to do with the magnets... Oh, and the light seals shrink in extreme cold (like snow) - I had an OM20 that travelled the world and was dropped many, many times, and batteries lasted forever in that and it only died recently.
Cheerio, Marc
