When I first got the lens I was not as impressed with it as I thought I would be. Now that I've spent some quality time with it I'm ready to jump on the bandwagon. It's quite remarkable. The image quality is wonderful. The sharpness, contrast and rendering are all terrific. It may not be a Summicron but it's easily the best native lens I have. I think my Pen-F 40/1.4 might be a bit better...maybe. I haven't taken it off since I got it. Who needs a Fuji X100? My EPL-1 and the 20/1.7 is just fine by me. The most interesting part of this is that I find that with the 20 the EPL-1 is just as useable WITHOUT my VF2 (AF is my friend). Angry Birds!
