Techart Pro is rumored to develop a new autofocus adapter that will autofocus M lenses on the Leica SL camera body – this is according to the designer/developer of the Techart Pro LM-E (Leica M to Sony E) lens adaptor in this Xitek forum posts (translation from Chinese):
Post #1854: ……is there the next generation [Leica to Sony] LM-E AF lens adaptor in the making?
Post #1855: Not within a year, now my focus is on Leica M-SL AF lens adaptor.
Update – here is another comment from a Techart Pro engineer:
“Although Fuji is good but it’s cropped sensor after all, won’t consider doing it, not at least till I completed adapter for Leica SL.In my heart adapter for SL is the real benchmark, I’ve tried wide angle lenses with SL, performed better than A7RII generally.”
