In this video I'm testing the new Techart Pro LM-EA9 adapter with my Sony A7IV and my beloved Leica lens - Summilux 50mm f/1.4 ASPH. This adapter makes Leica lenses autofocus with Sony cameras, which is incredible. This is the 2nd gen of the adapter - it's smaller, lighter and quieter then previous version and seems to be working great! Watch the video to see the photo examples and what was my hit rate of sharp photos.

It is exactly the test video I'm looking for! Very clear approach and good angle. Thank you. It looks like the AF is faster in the center than the concern.
The lens is the limitation here! We all know that the more corrected the lens design is and the more contrasty it is then Techart can do very well. Point it a a back lit subject and its going to start struggling unless the lens is super corrected and coated - thats why our modern AF mirrorless lenses are designed the way they are - super high contrast and sharp right across the entire frame wide open to that AF is optimum.
Amazing tech. Hadn't heard of this. Fantastic!
It’s pretty wild you can have af with manual lenses these days!
Impressed!
the firmware update thing being part of the lens cap is so clever!
Also - The LEICA SUMMILUX-M 50mm f/1.4 ASPH is a remarkable lens, being the world's only aspherical 50/1.4 with floating elements.
Floating element (non-unit-focus, internal focus) lenses: Some lenses have complex movements of internal elements relative to each other as the focus is adjusted -- they don't just shift the optical block as a whole closer to/farther from the sensor, which is what the Techart does. Any significant change from the set manual focus position is likely to degrade IQ somewhat. However, small changes will generally be fine. That's ok, it just means the lens should be set to approximately the right distance manually and the Techart simply tweak the focus.
having that kind of leica look and flair with AF is mind blowing...
Thanks magic for your work. It's very interesting. Just continue please. A frenchman
Merci! A polish men 🕺🏻
I have my LM-EA9 on order right now. Excited to use all my Voigtlander lenses on the A74. Thanks for sharing. Now this will probably get me over the regret when selling my SL system.
Did you get it? If yes then how does it work with a7iv ?
How is the weather sealing in this setup? More sensor dust or not? Thanks.
thanks for the review! i have the first version. if it's possible, I'd like to the how they compare... so happy that it doesn't have that bulging motor anymore.. 😆
Would you recommend this for video work too shooting manual focus?
I have the old techart 7( sold it) very looking forward for this new Version. My voigt 40 mm 1.2 vm can’t wait! . I even thinking on buying the voigt 50 apo VM because of this new techart
Let me know if you do and what’s your experience!
Can you use the Sony crop mode with this setup? Thinking about picking up a Voigtlander 35 1.4 with the adapter and use the crop mode to get a 35, 50 combo on a A7riii
Were the photos shown edited ? Interested to know how the straight out of camera Sony images look from the Leica lenses.
Thanks-
Hey Magic, it's been a while since this video so not sure if you still have this adapter. I just received mine yesterday. I have it on a Sony A7IV and was trying it with a Carl Zeiss 50mm F1.8 Pancolar lens. For reference I'm shooting using the rule of thirds grid lines. Focusing in the center rectangle is relatively quick and the photos come out pretty sharp. If I focus outside the center rectangle, it stills focuses (I get green confirmation) but the focus area doesn't come out as sharp. If I go more away from the center gets worse. I tried the same exercise but focusing manually and the image is much sharper when I move away from center. I was trying to make sure that it wasn't the lens glass that was worse towards corners. Do you remember if you had similar results with your adapter? Thanks!
Thanks Magic. Been waiting for some reviews on it. Hopefully Techart is already working on FW to improve the performance of AF-C. Also, have you tried it on low light situations? Like dusk or inside? Cheers
My pleasure! It seems to be working the same way indoors with artificial light and outdoors after sunset, but haven’t tried realllyyyyy dark scenarios yet
@@MagicWeddingPhotographer Yeah really dark I am not expecting to do a good job since even native lenses can struggle. But thanks for checking that out. I use these adaptors mostly with family so its nice that it can work properly.
nice tuto. how do you configure your a74 to switch so easily between wide tracking and spot tracking without going to focus area menus... ? why wide tracking ? isn't wide enough with eye detection ?
When you use tracking spot, whenever you half press on a subject to track it, the icon on the left changes to wide indicating the camera is following subject everywhere in the frame. Check my Sony A7IV af guide video - I break down all the options
Thanks for this! Do you edit all your photos on that m1 MacBook with 8c cpu 16gb ram and 512 storage? In description says that’s your main computer 😁 I would like to know how it holds up when doing like 2-3k photos and if it’s worth buying the 10c cpu with 32gb ram. Thanks 🙏
Hey Caciur! I have been using this computer as my main editing machine for almost a year. Recently switched to m1 max 14 fully speced mostly because of video work. For just photos m1 air holds up no problem. It’s not that fast exporting images or generating previews - but working in Lr itself is not a problem. But still - if you’re getting computer for years to come, I’d get 32gb ram.
hi magic, thanks for this interesting review! I just wonder if the walking shots would have worked better with back button focus - have you tried that before?
and another question: what whitebalance do you have on most these photos after edited? I tend to go from 6500 to 9000 during this time, sometimes I wonder if its correct.
Why would hitting another button cause a different behaviour?
Yeah I don’t think back button would change much. Shooting more like AF-S was the way here, as the continuous af just didn’t perform that well.
Regarding the white balance I like keeping images on the warm end - will double check WB value when I’m at computer and will get back to you!
@@flamonaut because you'ld have one button for focus, which you can keep pushing and one button for shutter only. no sense in using one button for two functions.
@@MagicWeddingPhotographer thanks! :)
I am your big fan and already bought this adapter after watching your video. May I ask you? Do you set lens focus at infinity position all the time? Even the subject is close than 3 meters, do you still set the lens to infinity position? Thanks.
Hey, thanks! I do set it from infinity, but at the end it all depends on the lens and focusing. I remember couple times just moving the focus on the lens when subject was super close. What's your experience?
@@MagicWeddingPhotographer I do the same. When the subject is very close, I move the focus on the lens. It helps the focus faster. And I found that this Techart adapter works like a extension tube of macro adapter. If I move the focus on the lens till the end of closest distance, I can take photo very very close to the subject with auto focus.
@@thanyawong Hi Peter, may I ask what focal length you found this kind of close focusing bonus?
@@xuchen1830 I use 50mm lense.
Hello :) One thing that is not clear in my mind ... Is it using for example a "Leica Summicron-M 35 f/2 ASPH. " on a body "Sony Alpha 7 IV " I will keep the angle of 35 mm ? Or will there be a reduction of the angle of view...
Same. It’s a full frame lens and full frame body.
Damn it sorry laaast again question :)
On the link you provide to Techart…
There is the "Techart PRO Leica M - Sony E Autofocus Adapter ver II (LM-EA9)" at $399.00...
But I 'm not sure why there are other rings on the page of this adapter... Between $50 and $120.
is this something we have to add, depending on the model of the lens we have… I guess ?
And if owning different Leica M lenses, we have to get different "small" adapters for each… Is it possible then to replace them every time by ourselves ?
4:16 this is and adapted lens and Sony made all of its cameras crippled to SLOW for the AF in burst shooting (it is written in the specs). You were on MED which means you had AF only on the first shot and after that the AF is not working (it just stops the AF). It is like that from A7III with all adapted lenses (canon, sony A mount, ... all of them). You can use LO burst setting which makes 3fps and it will work as good as it can. The only cameras that can work faster in burst are the A9, A9II and A1 - they can work with adapted lenses up to 10fps.
Autofocus work for video?
And last question !... Does the autofocus work mainly in the center of the lens ? Or does the facial recognition also work on the edges of the image ?
it's seems to be working better in the center of the frame. Although it still shows the recognition of eyes on the edges, but doesn't focus that well... not sure why
@@MagicWeddingPhotographer Thanks !
have you tried 4K video with this?
People seem to forget that the main limitation with these adaptors is the lens used!
Backlight, off centre focus, uncorrected lens design, low contrast etc etc are going to weaken the ability of the camera to AF this thing.
The design has not magically made the focussing ability any more effective! It maybe slightly quicker to move the lens and now have more stability with 4 motors but the limitations of using adapted glass are still there!
Looks like it don't work with Leica R to sony, only M mount unless I'm missing something
Correct, it’s for Leica M mount lenses
i guess you can add an adapter from R to M then use it on this adapter.
That flare is nasty. The adapter is really cool.
Zaborek?
Yup!

The manufacturer claims that the product has been significantly improved after long-term development. The price is with customs duty and import tax 500 + Eur. Why does the manufacturer not offer the usual and mandatory 2-year warranty in the EU, but only a 1-year warranty?
But doesn't work on A7iii!! Shit, bad news!
