Cheers for the feedback. I sent this image to the local Leica rep and he thought it was a bit over-sharpened on his monitor. He has one of those new 24" glossy iMacs. I'm running a Cinema Display (matte surface) and it looks spot on to me. It would probably look a bit soft on a CRT. I'm curious as to how other posters are gauging the appropriate sharpness given the potential disparity in viewing monitors.
