To respond to the original topic:
I recall family friend Malcolm Crowthers, an accomplished pro photographer based in England, using a Nikon F2 body plus two Olympus OM cameras. His website is here:

They ain't no Nikon F or Canon F1.
Agree. I liked the OM-2 when a friend loaned me one for a week. Solid enough but no way as tough as a Nikon F, Canon F1, or Nikkormat.
I did not let myself get seduced by the big viewfinder. And i did not like having the aperture ring further away from the body. As for the innovative, revolutionary OTF metering, i couldn't care less; the flaw is that you can't see the actual exposure metering by the OTF sensor; what you see in the viewfinder is the metering done through the prism by two CdS cells which have a color response different from the OTF sensor (which is a SPC cell). Boo!! In any case, in-camera meters are for wimps (unless you are a photojournalist, in which case the OM-2 auto mode is a god send).
Nice camera but i have been more impressed by Nikon, Canon, and Minolta bodies.
