So my 5D2 is for sale since I'm trying to buy a 5D3. Had a guy drive an hour to buy my newish 5D2 for a really good price.
He brought his 550D (T2i I believe) and his 35mm f/2.0 to compare. He used his lens on my 5D2 and his 550D, and the images (when zoomed in all the way) appeared sharper on his cam even after we fiddled around with micro adjust. He was kinda put off and didn't buy it. No big deal.
It didn't occur to me then, but I later realized that his pics must have appeared sharper due to the crop factor since a 35mm on a crop is more magnified.
Is that what happened or do I have a crappy 5D2?
