Fantastic Photographic Tool for the Manual Lens Enthusiast
I received #869 but sent it back for repair and got #425 back in it's stead. So, i am a fairly early adopter who ordered this months before it was released. Anyways, onto the review.The focusing is crisp. Fast and accurate. When pixel peeping say @ 300%, manual focusing without adapter while using maximum focus peaking is marginally better than when using adapter to auto focus. However, I require the adapter's service when 1) I need focus fast and when 2) I am using large aperture lens that's nearly impossible to manually focus in under 10 seconds such as when using Voigtlander 35mm 1.2 and Nikon 50mm 1.4 at or near max aperture.Although the adapter is designed for Leica M mount, I use a plethora of vintage Nikon lenses with a Fotodiox Nikon to Leica M adapter. My favorite to use are the aforementioned 50mm 1.4 Kogaku and the 55mm Micro Kogaku.Also, after updating driver, the adapter can now pre-focus then recompose. Before this update, it was impossible to get something not in the center of the frame to be focused.I am reliant on this adapter when shooting at max aperture as I can only achieve a 10% rate of getting the focus right as the DOF is razor thin. Whereas, the percentage is about 90% when using the adapter to auto focus. Although, subjectively, when I manual focus, the shots are generally a tad sharper, but it takes me longer to compose and focus, and, especially when shooting people, I miss a lot of good shots this way.Now, room for improvement:1) When installed, the bottom portion of the adapter is too close to the camera's tripod mount hence prevents tripod or connection plate from being screwed into the camera's tripod mount. Maybe shift the "box" portion to the side.2) No way to turn auto focus off when adapter is installed. There should be an option to turn auto focus off. When in focus menu, the manual focus option is grayed out when adapter is mounted. Maybe a driver update to allow manual focus to be selected or just be able to turn the adapter off even when installed on camera.3) Maybe 1 out of 100 exposure attempts, the adapter gets stuck and needs to be turned off then on in order to reset.4) Exposure actuation speed is great for normal use but too slow for moving objects which I know is outside of the product's intended use but would be great if this could be improved. Maybe a manual focus assist option.5) Instead of multi point focus, I'd like to be able to use single point focus with ability to adjust focal point.Customer service: I did accidentally drop my camera once while the adapter was installed. The adapter was banged up and stopped working. And, Techart covered the repair and returned it to me in less than a week. Basically, they replaced my damaged one with another.

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.
If the user is not too concerned about focus at the corners and if the user uses higher f numbers this device could be useful. There is also the question of manufacturing tolerances. Different samples might be much worse than the sample tested.
