I have both a Nikon F100 and Nikon F80's and when I go out on the motorcycle it is nearly always the F8 that comes with me. Sure it is nearly all plastic, but what isn't these days. The metering is more or less the same as the F100, in a smaller and much lighter body. Don't forget the Olympus OM2n is going to be AT LEAST 30 years old and they don't last forever. Stick with Nikon and you have all you want.
