So I ended up getting the Olympus OM4 and I have to say I love it. The OM1 is a great camera but the OM4 has a certain feel about. Ah heck I like both! But carting around the OM4. Love the size and weight.
It ended up being a version with what looks to be a lower drain board as the battery test turns off after about 15-20 seconds.
Took this camera to Portland and accidentally left it on a few times but seems it has an auto-shutoff feature... or atleast, it stops auto meter relight if I don't hit the shutter button.
