The one thing that can be said for the OM3 and OM4 variations is that they have what is probably THE best metering system in any 35mm manual focus camera. The way the multi-spot system works is that each time you press the spot button you record a reading, up to eight readings, and when you press the shutter release, the camera averages the readings...It gives you what is, in effect, a built in Zone System. You can, of course, just use the spot meter to take a single reading, off a face, for instance. You can also lock the readings in with the Memo function. There are also two additional buttons, for highlights and shadows. If, for instances, you're shooting a scene at the beach, or in snow, you take your reading and then hit the highlight button -and it increases the exposure by two stops so that white is white, not 18% gray. If you're shooting something with deep shadows, or black in it, and what that to come out as black, push the shadow button, and it decreases exposure by two stops and black is read as black. It's pretty nifty.
