The impossible has been made possible. Camera MX transformed a Leica Summicron 35mm f/2.0 manual focusing M-mount lens in a sort of E-mount version with full autofocus support! You may argue how the heck that can be done…so here is the text I got form the “inventor” of this solution (from Chinese companies MX Camera):
“We put a Leica M 35mm f/2 into a Contax G Biogon 28mm f/2.8. When use with our Contax G – NEX AF adapter, it will come a NEX-AF lens!! And the result is quite good! We will make a video for it very soon. We try so many different Leica rangefinder lens and the result, the best match is 35mm and 50mm f/2 or small aperture lens with Biogon 28mm lens body.”
And they are now going to test the same “technique” with the 35mm f/3.5 (here on eBay), Summicron 35mm f/2 (here on eBay), Summicron 50mm f/2 (here on eBay), Elmar 90mm f/4 (here on eBay). There is no plan yet to commercialize that kind of lenses.
