Leica M Mount Lenses Can Now Autofocus Using Camera MX

Leica M lenses have forever been known for their buttery smooth manual focusing. But recently, a new company stated that they can now make these lenses autofocus. Sony Alpha Rumors states the the company is called Camera MX, but we’re not too sure about that one after doing some Googling on that name and DEO-Tech.

So how does this technology work? According to Sony Rumors, the company stated, “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.”

This seems pretty crazy, and I’d love to see a video of it. But this is exciting news anyway. In turn though, it may drive Leica M glass further up even more. Let alone we’re not sure if they can develop a motor system strong enough to move the elements inside of the 50mm f0.95 Noctilux.

Strange – not only do you need a Leica lens, but also a Contax G lens mount to put it in. I can’t imagine that is a particularly easy operation.

This article makes no technical sense. An M mount lens communicates to the body in the opposite direction as an autofocus lens. The lens has a cam that adjusts the rangefinder mirror. To autofocus an M lens, one would need a motor to turn the focus helical. Many people hate manual focusing with Sony lenses because of their “focus by wire” absense of drag that makes an M lens a pleasure to focus.

If the system involves remove of the lens elements from an M mount lens, “faggedaboudit.” I own 3 M mount lenses and a lovely screw mount 135mm f3.5 Canon that I use on my NEX-6. Combined with the Sony’s P setting and edge enhancement function, manual focusing them is a snap. This appears a very costly “cure” for a non-disease. If you can’t manually focus an M mount lens on a Sony E mount camera with its excellent EVF, don’t call yourself a photographer.
