Thanks for those, Rico. It looks like what I've noticed between the X100 and the 23 f1.4 lens: At f2, the X100 lens is noticably softer. The f2 and f1.4 lenses seem to perform almost identically, which is impressive for the smaller lens.
Yes. There have been reports of softness with the 23mmF2 at short distance and wide-open. I couldn't confirm that (didn't really test at MFD, and the bokeh samples look okay), but I remember having that with the 35mmF2 pre-production sample.
