"Old fondler lenses don't do well on modern Leica digitals. Even Leica have moved away from those and have been designing better lenses."
Rarely do I want to reply 'that's just wrong,' but I guess I'll try it.
IMO if you made the point correctly it would be that Leica is now making lenses that optimize for higher resolution and contrast, period. But this doesn't for a moment imply that older fondler/Mandler lenses "don't do well on modern Leica digitals."
It only means that modern sensors and older fondler/Mandler lenses, when combined, offer the advantages/disadvantages of lower resolution, lower contrast, and other things you don't happen to value.

Homage to August Sander; MM with Mandler lens – not quite as old as these two guys
