From what perspective are you interested? The absolute res will
only be as good
as you'll see out of any of the Pentax DSLRs since it uses the same
sensor.
There seem to be plenty of reviews on-line, most however appear to
concentrate
on edge performance and vignetting. In most instances the Leica
lenses provide
improved results over the Cosina lenses but most WA lenses do seem
to vignette
a little more than they did when used on film bodies.
I saw no real difference in image quality between lenses made by
Cosina, Konica and Leica. For that matter, some of my Russian lenses
looked as good.
With film the limiting factors in resolution are the size of the
silver halide crystals and the thickness of the emulsion. With
digital it is the size of the individual sensor elements, the
smallest of which are far larger than the crystals in any modern film.
In digital the appearance of sharpness is created by the firmware/
software used to process the image, not by lens resolution. I think
that lens contrast is far more important for digital than raw
resolution.
