On the other hand, what Reichmann says about Leica M lenses is a bit of a red herring. The Leica M (and other rangefinder) WAs were originally designed for film and their lack of telecentricity is a problem with digital sensors since the light destined for the edges of the sensor has a fairly large angle of incidence. This may cause problems with vignetting (due to poor utilization of the light that comes in at such angles) as well as edge sharpness and purple color casts (due to crosstalk). Leica is now forced to work around these problems in various ways. These digitial-specific problems aside, the old rangefinder WAs also have problems with so-called natural vignetting. See here, under "Natural vignetting" for an explanation:


I think MR himself compared some time back a Leica lens on a m43 camera (or was it APSC) and the outcome was not that great. So far I remember the Leica lens was just a bit worse to a native lens for that mirroless system.

Would not be that a big surprise if the outcome on a mirrorless 35mm camera would be somewhat worse to a native lens for this system.
