Read the subject line. FF on 5D

Whoa! Where did that come from? There's no mention of cropping, the format is 
perfect 3:2. All the care given to moving 
the tripod for equal framing with different lenses would certainly suggest no 
need post capture cropping, in fact, the 
reverse.

I've already posted that it's not a very good test without some unreduced 
samples. And yet ...  Both Chris and I in some 
way saw the first one as in some way less sharp.

I think maybe even with the considerable downsizing, perhaps particularly 
without resharpening, there is still something 
subtle that those with good eyes can pick up on.
