My good friend left to asia for 3 weeks and left me his 1DS so I thought I'd see what kind of difference I would see between my 1d classic and 20D I used a Canon 50 1.4 exposure was: iso 200 1/80 f/1.4 All three are shot RAW with +3 sharpening in canon DPP then resized. No cropping. Center point AF on eye. Can you tell the difference? 1. 2. 3.
