Nice camera, small & light (certainly can't say that for the F5/6). However the viewfinder screen is effectively fixed and the metering is unsophisticated. Mind you it does work as a fully manual camera (without batteries, only the metering is lost) - that's worth a lot. If you can't afford an Olympus OM3, certainly worth consideration.
