[Leica] Advantages of M lenses on the SL compared to R lenses? Adapters?

[mark at rabinergroup.com (Mark Rabiner)]

I think I'm seeing both sides of the new lens sizes issue a little bit. 
After years with the tight restraints of designing glass for the M system 
Peter Kolb and others lens designers seem to be having a ball with the 
generous lens mounts in the new mirrorless cameras giving them true room to 
breathe.  They are way wider than Nikon F, And Canon etc. established from 
the early SLR days though they didn?t have to worry about blocking a 
viewfinder window.  Nikon is celebrating by coming out with a .95 lens soon 
called a Noctilux I'd have thought that would be a Leica trademark. So they 
are also having a ball with the huge new mounts.
In the past year or so I've re bought Nikon 1.8 primes in 35, 50, 85 focal 
lengths and which are as if someone inflated them with a bicycle pump.  They 
are inflated and hollow feeling. The filter sizes are several sizes larger 
than the 52mm standard size of the classic SLR's. They don't look ill 
proportioned on the DSLRS they are designed for though and balance perfectly 
and better than my old compact D glass for the most part. So even on small 
old mounts lenses are designed way more generously than before. All the 
elements have room to breathe.

That said these huge zoom lenses made now to put on the front of the new 
flat, compact mirrorless cameras I'm not sold on getting myself. Getting 
into mirrorless I'd use Leica M glass and a Nikon Z lens would have to be of 
near pancake proportions for me to bite. I think maybe one is so far.  I'm 
not going to mount an air to ground missile on the front of scaled down 
compact cutting edge designed camera body.. Might just ruin the unobtrusive 
feeling of the body design. Part of good lens design to me is to not lose 
sight right in the beginning what the camera system is supposed to be all 
about. Mirrorless to me seems to not be about metal munching monsters. But 
compactness and flexibility. And video. And keeping up with the Joneses.

    I thought the discussion was about SL and M lenses.
