Just a short blurb before sleeping, as editing has consumed my night and I haven't been able to play with it much, yet. I've got and have used sharp lenses. My 85/1.2 stopped down is sharp. TheGirlfriend's 70-200/2.8 is sharp. My 300/4 IS is sharp. This 80-200/2.8 is SHARP. Built like a tank and optics in nearly perfect condition (there's exactly 1 speck of dust near the edge of one of the internal elements, not bad for a lens with a date code putting it at 23 years old), it's no wonder why this lens helped Canon steal the sports photographer marks from Nikon back in the 80's.
