Techart PRO adapter is the world's first autofocus adapter for your manual focus camera lenses. It is able to turn your manual Leica M lens into an autofocus lens and use it under the Sony A7 cameras. Not only does it immediately give lives to all the manual Leica M lenses, it also changes the experience they had with these lenses. You can now use your favorite Leica lenses for taking snap shots, motion pictures or candid photos. &#149; Turn your Manual Focus Leica M-mount Lens into Auto Focus &#149; Fast & Precise Focusing for Snapshot / Motion photography &#149; Support AFS & AFC mode &#149; Further adapting other lenses with other bayonet mounts &#149; Improve Close Focus Ability &#149; Super Light and Compact &#149; Compatible with Sony A7(II) & Sony A7R(II)   How does Techart PRO adapter work   Techart PRO adapter is basically a lens adapter with a motor and a printed circuit board, allowing the camera to measure the focus and communicate with the motor. And the motor will move the lens closer or further away from the camera sensor to reach the focal point. The principle is similar to the Contax Ax camera that the flange distance is adjusted to reach the focus. The maximum z-shift is 4.5mm which is sufficient to cover the focusing distance for most of the lenses. And the optical performance will NOT be affected for unit focusing lenses.   What makes it so evolutional    Fast & Precise  Techart PRO adapter has to be fast, precise and stable. They have carefully selected a motor which can drive the lens as fast as a native AF lens and stop instantly when the camera instruct it to stop. The focusing takes less than a second and the picture they had is really sharp with precise focus.   Support AF-S / AF-C Mode  Techart PRO adapter does not only support AF-S, but more importantly, it supports the AF-C, the continuous autofocusing mode. This is extremely useful for shooting moving objects like sports players, children or animals. In the past, you may not be able to keep these photos sharp with your favorite Leica M lenses, but now you can certainly do it with the Techart PRO adapter.   Improve Close Focusing Ability  Techart PRO can improve the close focusing ability of your lens. It serves the same function as the helicoid or close-focus adapter in the market where the minimal focus distance of the lens will be shorten. This overcomes a limitation of most Leica M lenses which does not allow to shoot really close. You can start taking macro-like photos with Techart PRO.   High Compatibility  Techart PRO adapter is also highly compatible. It can accept lenses with Leica M bayonet mount and connect them with Sony A7II and Sony A7RII. You may also further adapt other lens mounts with longer flange distance like Leica R or C/Y mount to Techart PRO adapter so that these lenses can also be vitalized. This opens up a tremendous amount of lenses options to be used with Techart PRO for auto focusing.   Light But Powerful  Leica M lenses are light, compact and perfect. To pair up with them, Techart PRO is super light and weighs only 133g. It is compact but it does not mean weak. The motor is so powerful that it can drive a lens system as heavy as 700g.   Supports the 5-Axis Stabilization  Techart PRO allows you to save 10 sets of lens data, including focal lengths and aperture values, via their complementary mobile app. The camera body will be able to make corresponding adjustments based on the focal lengths for using the 5-axis stabilization.

I love that this adapter has given me af access to so many vintage lenses that I own. Love it with the nikkor 105mm 2.5 on the a7rii

Works very well

Techart PRO Leica M Mount Lens to Sony E-Mount Camera Autofocus Adapter

Review by Norman Rogers

I used this device with a Sony A7R2 and several different Leica M lenses. I noticed that different corners of the photos became blurry randomly. It seems that there is play in the mechanism that causes the lens to be tilted with respect to the sensor plane.

Here is an example of sharp and blurry corners using a Leica 90mm f2.0 lens.



I noticed that if I pushed on the lens it would wobble slightly with respect to the camera.

I disassembled the Techart device using JIS Screwdriver to remove the two screws holding the black metal cover.


The lens carrier is moved by a stepping motor that drives a rack and pinion through a reduction gear, The lens carrier slides on two linear bearings, a large one and a smaller one. That is the only support for the carrier, so it is cantilevered over quite a distance and can flex.

This is fundamentally a bad design, There needs to be 3 point support of the lens carrier, probably using a spiral cam that engages the carrier at 3 points.

Techart seems to have the software down pretty well, The device focuses quickly and accurately, but the corners will often be off focus.

Techart Autofocus Adapter Wobbles

First one failed after a few hours. Second one too slow for me, had to almost manually focus and use the Techart for critically finish focusing. Many with better sight than me will adore this so there is both a problem with my sight and a problem with the Techart in that is finishes way, way behind native E mounts in focusing speed.

Very Nearly a Must Have Product

I use this on an A7ii and could not be happier. 

I have been shooting with the Techart adapter for a couple of weeks now and am satisfied. I can now use my small collection of rangefinder M and LTM and (with additional adapters) my Pentax K, Canon FD and M42 lenses with autofocus. 

The documentation for the adapter is, to put it kindly, a bit sparse. Be sure to visit fred miranda dot com's Techart FAQ to get yourself up to speed. 

Off center focusing and attempting to use the adapter's autofocus capability in very low light can be somewhat frustrating, but in those situations I usually would use manual focus anyway - with these manual focus lenses.

There is still the issue of the adapter slowly draining the camera battery even after powering down the camera UNLESS you pop the camera battery out for a moment, then replace it. Another minor issue but worth mentioning.

Very happy with the purchase.

Brings old glass back to life

I have been very impress with the tech art pro adapter with shorter focal lens.  The auto focus is very fast, like the auto focus of the zoom kit Len  on the mirror less sony camera.
On telephoto lens, it is a little slower due to the length. To speed up auto focus, need to estimate how far you are from the subject, which is call dirty focus help, then will focus.  You could use aperture priority, which is recommend, will still work with speed, manual mode to auto focus, dial to infinity and f-stop to the widest like 1.4 /2/2.5. Can still control in the camera f-stops in the aperture or manual mode.  Thanks,  David Koo 12-9-16
