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 we had with these lenses. You can now use your favourite Leica lenses for taking snap shots, motion pictures or candid photos.
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.
FAST & PRECISE
Techart PRO adapter has to be fast, precise and stable. We 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 we 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 continous 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 favourite 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.
LIGHT BUT POWERFUL
SUPPORTS 3-AXIS STABILIZATION
We have run testings with a lot of Leica M mount lenses and the performance is very stable. Below shows the testing videos from our users. Will keep updating.
1) Testing with Leica 50mm f/1.4 @ f/1.4 with Sony A7 Mark II (0:00 – 1:11)
2) Testing with Voigtlander 35mm f/1.2 @ f/1.2 Mark II with Sony A7 Mark II (1:12 – 1:54)
3) Testing with Voigtlander 15mm f/4.5 @ f/4.5 Mark III with Sony A7 Mark II
(1:55 – 2:42)
1) Testing with Leica 90mm f/2 @ f/2 with Sony A7 Mark II (0:00 – 0:47)
2) Close Focus Test with Voigtlander VM 35mm f/1.2 (II) at designed closest focusing distance 0.5m.
The distance shortens to around 0.2m after using our Techart PRO adapter (0:48 – 2:21)

Frequently Asked Questions
Q: Where should I set the focusing ring when using the Techart PRO for autofocusing?
A: Normally you should park the focusing ring at INFINITY focus and use the Techart PRO for focusing.
Q: Is the 4.5mm extesion enough for my lens to autofocus for the whole focusing distance?
A: According to our testing, Techart PRO can cover the whole focusing range for lenses with 50mm focal length or below. You can simply park the focusing ring at infinty and press shutter for autofocus. For lenses with longer focal length (>50mm), users may need to coarse adjust the focusing ring to the focus point and use Techart PRO for fine focus adjustment.
|Focal Length||Focusing Range|
|15mm||6.5 cm – INF|
|21mm||12 cm – INF|
|24mm||15 cm – INF|
|28mm||20 cm – INF|
|35mm||31 cm – INF|
|50mm||60 cm – INF|
|90mm||1.8m – INF|
|135mm||4.2m – INF|
Q: How does the focusing work and what is the difference versus focusing via the turning the focusing ring?
A: The focusing is done by adjusting the distance between the lens and focal plane (sensor). There is no difference in terms of image quality for unit focusing lenses.
Q: Is Techart PRO compatible with all Leica M lenses?
A: Techart PRO is compatible with Leica M lenses weigh under 700g.
Q: Can I control the aperture of the lens?
A: You will need to adjust the aperture on the aperture ring of the lens. However, you can record the aperture value to EXIF by setting through our mobile app.
Q: Can I further adapt lenses mounts with longer flange distance to Techart PRO for autofocusing?
A: Yes or No. You may adapt lenses mounts with longer flange distance to Techart PRO for autofocusing. Currently we have tested several lenses with Leica R mount or Contax/Yashica mount or Minolta mount and they work with Techart PRO perfectly. However the whole system has to be ligher than 700g for best performance. For lenses with larger thread, further adaptation may lead to a ‘double-aperture’ OR ‘Vignetting’ which implies a potential impact on optical quality. Please consider before purchase.
Q: Can I use the Techart PRO for video shooting?
A: We do NOT suggest using Techart PRO for shooting videos and only MF is available for video shooting.
Q: Why my Techart PRO is not working with my Sony A7ii?
A: Please make sure your Sony A7ii camera has been upgraded to the latest firmware where the 3rd-party PDAF function was unlocked. This adapter requires the 3rd party PDAF function to work.
Q: Can I use Techart PRO with other E mount cameras other than Sony A7II & Sony A7R II?
A: We have optimized the Techart PRO to use with Sony A7II and Sony A7R II only (A6300 TBC). You will get the best performance with these two cameras as they support the 3rd party PDAF. We do NOT recommend to use with CDAF-only E-mount cameras (i.e. Sony A7, Sony A7R, Sony A7S, Sony A7S2, Sony A6000, Sony NEX, etc)
Q: Will the image quality change when focusing with Techart PRO compared to MF adapter?
A: For unit focusing lens, the image quality will be the same as turning the focusing ring to focus on Sony A7 series cameras. For floating elements design, image quality may be changed. (FYI, Most of the Leica M lenses are unit focusing).
Q: How to shoot Macro photos with the Techart PRO adapter?
A: You should park the focusing ring of your lens to the closest focusing distance and use Techart PRO for autofocusing. You will then find that you can shoot much closer than you normally can shoot.
Q: How much weight can Techart PRO bear?
A: It can support lenses as heavy as 700g. However, we suggest users to slightly support for heavy lens (>300g) in order to enjoy the best focusing performance.
Q: When will I get the Techart PRO when ordered?
A: We will start shipping the pre-orders from late March 2016 onwards. For US / EU orders, it normally takes less than 7 days to arrive. For other orders, it normally takes around 10-14 days to arrive.
