It might be slow, but it's definitely autofocus
A Hong Kong based company has developed a lens adapter that will do more than just let you mount Leica glass on your Sony NEX. For the first time, it seems someone has created a way to make those Leica lenses autofocus on an E-mount.
This comes from Hong Kong companies MXCamera and Deo-Tech. According to reports, the process involves going from Leica M to Contax G, and then using that to autofocus with. As the creators described it:
“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.”
You can see the final result in the video below. It's slow, but that's definitely autofocus. According to SonyAlphaRumors, MXCamera plans to modify and sell five Leica lenses: the 35mm f/3.5, Summicron 35mm f/2, Summicron 50mm f/2, Elmar 90mm f/4. That makes it sounds like this will be a permanent modification to the Leica lenses to make the system work, rather than a hodgepodge of adapters.
