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

[Robert Baron]

Mark, as I understand it the big lenses for compact mirrorless bodies are
big because of the autofocus mechanical innards they require.  I would
enjoy my new Nikon Z6 a whole lot more if I had a much smaller lens to put
on it that would still autofocus and I hope and think that such will be
available in the next little while.

In the meantime in addition to the 24-70 f4 zoom that is a right nice 'kit'
lens I bought the prime 50mm 1.8.  It is no pancake but at least it doesn't
extend itself beyond all propriety and gives me a focal length that brings
back memories of the fifties and HCB.
