The 50mm lens renders pretty nicely (judging from the sample images). A bit less impressed by the more expensive and elaborate 105mm lens concerning specular highlights and how they shape bokeh (again, judging from the sample images available).

But they appear to be quite nice lenses.

Based on the MTFs that Markus showed me, many of the Zs are pretty spectacular - plus the occasional dud.
