Just noticed that photozone have just completed thier DZ 11-22mm review/lens test....along with the 14-45/14-54/40-150 some time ago.... the 50-200 should be coming out soon....
Needless to say, this lens performs ...small, fast AF, barely any distortion, almost no vignetting, excellent MTF....especially for an ultrawide
here's the link....
