@HDNitehawk in the comparisons of the 1DS3/5D2 cropped images vs. the 7D's were those pictures shot with a longer lens on the FF cameras or using the same lens? Using the same lens in enough light I'd expect the higher pixel density of the 7D to win (ignoring AF, etc.) if the glass is good enough. Mind you, that's some good glass. However, if I were to reshoot the same shot so that my object were framed the same I'd expect the more pixels of the FF sensor to have superior IQ - and FAR better high-ISO performance to boot. Of course, one can't always go buy lenses 60% longer than they've currently got at the same f/# so the point is moot. I was just curious (as all the FF cameras are out of my price range at the moment but the 7D may be close).
