Some choice quotes regarding the lens:

It is clear that this lens is capable of resolving beyond the definition of the M9 and MM sensors...
Peter Karbe wrote:
The lens will of course only reach peak performance in conjunction with the M9 Monochrom because it has the resolution and the entire imaging chain is so lossless that it’s only then that the performance of the lens comes across.

The performance of the lens is flawless. For what it is worth, the ASCR at full aperture (f/2) is able to resolve 160 linepairs/mm on microfilm, developed in Spur chemicals. The lens therefore has a large quality margin for use with the M8/9/M-E/Mono with the 6.8 microns pixel size (70 lp/mm) and the M with 6 microns pixel size (80 linepairs/mm).
