The DP2m is capable of insane sharpness and clarity for its size. I've recently compared a DP2m 20x30" print to a M9 w/ 35mm C-Biogon 20x30" print and the Sigma was indeed the winner in the clarity and sharpness department. Amazing camera that most people will never bother with. I'm glad I did. At this point, the only thing that bothers me is there is no LR support.
