Techart Pro Review and Compatibility List

If you follow Sony Addict on Twitter you know I was recently in NYC testing the Techart Pro adapter at B&H Photo with our contact Abe. I have been shooting pretty much exclusively with this adapter on my Sony A7M2 since receiving it, and firmware 3 fixed the vast majority of crashes I experienced during my first stress test shooting a show. If you’re a fan of Leica glass and own a Sony body the TechArt Pro is a must have accessory.

I can only say this with confidence because I personally tested 73 lenses on the Techart Pro and only TWO failed to work correctly! That’s right, TWO, the Leica 90mm Macro-Elmar-M f/4 (but I would like to try a second copy because of it’s unique design) and Voigtlander f4.0 Color-Skopar 25mm f/4 P (the lens was too wide at the base and pressed against the adapter).

There are other things I learned about the Techart Pro by testing such a large variety of lenses. For reference when you first mount a lens on the adapters it should be focused on infinity for the adapter to work optimally. Lenses wider than 35mm almost universally macro focus, while 35mm lenses have negligible macro capabilities when set at infinity. “Normal” focal length lenses, around 50mm, focus as per specification. Beyond 50mm the majority of lenses need to be moved off infinity to close focus, and they generally do not have macro capabilities. Even the Noctilux will focus, but it is right at Techart’s  700g recommended weight limit, so I would be careful with this lens attached if you are going to use it for extended periods of time.

The physical gear inside that moves the lens closer and further from the sensor moves all of the lenses at about the same speed, so I do not feel it is important to reference focusing speed beyond saying that this adapter will let you track with an M lens, but focusing from infinity to a meter away isn’t fast. The Techart adapter is best at making quick adjustments between a few feet and inches, which will satisfy most users. It is also far from silent so the adapter isn’t usable for video.

When I was testing the adapter in the store, employees and customers were impressed by how well it worked and I didn’t even demo how easy it is to update. No one is doing firmware updates as conveniently as Techart at this time. I love their implementation of Bluetooth, where I set my camera to F90, press the shutter button, turn the camera off, and let the app do the rest. No pairing required, and all from my phone. You can even downgrade your firmware from the app if you have an issue or a preference.

It’s hard to find anything wrong with this adapter, and I tried my best to find things that wouldn’t work. My only issue is a nitpicky one, but I would like a way to write metadata to the raw files with the correct lens names via the app. Techart just made the app so easy to connect to the camera that I think they should exploit the feature further by adding a text field or drop down menu so that we can name the lens that is attached. I know this could make things more difficult if someone switched lenses and forgot to change the name, so they could also implement a feature that reset the name when the camera is powered off completely. A feature like this would be a time saver for many that like highly organized Lightroom catalogs.

Below you will find a list of all of the lenses I tested in black (I also tested silver/chrome because they are heavier and many are made of brass, but I didn’t include links to them order to condense the list below). If they worked normally, there is no marking by the name; but if they have macro capabilities there’s an *, and if they need to be moved off infinity to focus close I marked them with **.  I also put a legend below the list. Once again, I must thank Abe and B&H Photo for their hospitality and assistance. Without them I never could have gained access to this many lenses, and there might be a few more on the way soon. I’m going to do my best to keep this list up to date and I am accepting glass to test if anyone has anything obscure to test.

    Do the lenses focus slower when stopped down?
    At least that’s the way PDAF works with native lenses…

    • No. It’s very mechanical and uses PDAF. I started doing individual lens analysis, but performance is homogenous.

      • yaley

        So if you put a Leica lens on it and stop it down to f11 or even f16 it will still focus the same as wide open?
        That would contradict a couple of other reviews I’ve seen…

        • I did not experience any difficulty in store doing the testing, but testing every single variation would be a bit extreme. Also keep in mind that there have been a few firmware revisions so things could get better or worse, but I tried wide open/4/8 quickly without issue on the lenses listed below. At least once.

        • Peter Saputra Sulistyo

          yes its hunting and small aperture require good lighting. in low light use <f2.8

          • That’s simply not true… It doesn’t hunt, but slows like PDAF does in very low light. I just tried it under some pretty extreme circumstances with my 50mm and one covered 60 watt bulb at night in a pretty dark room.

            I focused on a few objects on the far end of my room and some up close with my 50mm at f8 and f11 and it would quickly get close to exact focus, but then creep till it locked. It never went back and forth like CDAF hunting does. It locked each time, but failed at f16.

            I am pretty sure no one would ever shoot like this, but it’s not too bad. By comparison my 50mm f1.4 Planar could lock at f8/f11/f16, but did hunt quite a bit before locking successfully, but it has the advantage of being able to control the aperture. It’s basically 1.5 seconds to focus vs 2.5 seconds to focus. Not really something to ding the adapter on.

            Now I did ding the adapter previously for crashing, but a lot of that has been corrected.

          • Peter Saputra Sulistyo

            Really?i tried indoor at f8, it took me 5-8second. do i get a bad copy? i wouldn’t recommend using aperture if it hunting so much. i will missed so much moment. i wouldn’t call it working. it is recommended below f2.8.

          • Yes really. It’s basicly as fast as the Sonar. Neither lens did great under such extreme lighting, but both locked. You might have just been running old firmware and to further clarify I purchased my adapter and in no way shape or form make money on the sale of them. I just love Leica glass and I’m excited by how well this combo works.

          • Peter Saputra Sulistyo

            i’m running v3. is it the same with you? i’ll try it outdoor tomorrow. i hope mine is ok.

          • Are you running the one marked as PRO or EA-7? I think there might be some slight differences. Also what firmware version do you have on your body and of course do you have PDAF turned on… try AF-S vs AF-C etc… the adapter works better than some of my Sony FE lenses. I was a little hard on it about the crashing in the past, but since 3.0.0 it has run smoothly for me.

            The thing that I find funny about the TechArt Pro with my 50 lux vs my Planer is that it’s so much smaller, but is optically superior to the Planer. Someday I’ll have to do a comparison.

          • Peter Saputra Sulistyo

            i’m on firmware 3.3 on a7rii. adapter v3.0.0 20160626. phase detect on. af-s. it still crashing from time to time. do you know how to check the adapter firmware? i want to double check it

          • Lens info… just try reflashing the adapter. Maybe you had an issue. Also try switching between single and continuous. See if something different works better for you. The difference could also be between the regular A7 and A7R. We both have Mark 2, but I was waiting for a Mark 3 to invest in a R camera since they were on the market for almost a year when I bought mine. Sony cycles cameras too fast.

          • Peter Saputra Sulistyo

            yes2 i agree with you, mark 3 will be the absolute ultimate camera for me. i’d like improved evf and lcd quality. i tried fuji x-pro2 evf is just mindblowing. i heard the SL is still the best. but i never tried it.

          • The SL EVF is like looking through a window. Very medium format like. X-T2 is about as close as it gets to that size/quality. Sony is falling behind.

          • Frank Filippone

            To me, this brings up an important issue. I have an A7. The first model. Techart says the adapter works only with the Mkii lenses aind not the original. Can you tell me from experience that it works with the original A7? Are there any limitations that you have found vs the A7Mkii?

          • The MkII cameras are open for 3rd party development access. I’m pretty sure Sony never allowed access to the original cameras so I doublet the adapter will work on it, but you never know.

          • Frank Filippone

            Louis. I understand that V1 cameras were not open to third party support. However, the question remains as to whether they actually work, in practice. Certainly someone has tried. What results were found?

          • From the manufacture

            “Because the adapter works with PDAF and Sony does not unlock the 3rd party PDAF support for original A7.”

            I asked why it does not work and this was their response. They also said that others tried and it doesn’t even try to focus…

          • Frank Filippone

            Thank you. Your last comment really scares me off from purchasing one tontry out. Maybe, if/ when I upgrade to a Mkii or iii….
            Very much appreciated.

  • John Görten

    Yo can add the leica 90mm Elmarit-M. Works without any problems on the A7RII and A7II

    • Firmware 4? Same one linked above? Also did macro work? How was the speed. I need a little more to go on.

  • Albert

    What about corner IQ for wide angle lenses eg: <=28mm? Are you using a Kolari thin filter mod?

    • The adapter doesn’t provide/promise any IQ improvement over other adapters. I didn’t notice any offensive fringing while testing, but if you take a canon LTM lens and throw it on there it will have purple fringing just like with any other adapter.
