[Leica] Big SL Lens ( DIameter) explanation

[Don Dory]

They are using stepping motors so more alike the focusing Sony uses on
their G series or like Zeiss used on their autofocus camera that moved the
focal plane.  Quicker, quiet, and extremely precise as they stop
immediately for all practical purposes.  If you go back to the Lensrental
blogs you can see how single focal length glass is better with lower
individual unit deviation, so I am glad that the major optical houses are
offering really good single focal length glass.

Really, with the M adapters you have your choice; small light and M glass,
or autofocus and a much larger lens of "equal" optical quality.  Other than
price who is against choice.
