Get autofocus with manual focus lenses on Sony E-Mount cameras! (Techart LM-EA9 Review) 

That’s what I was just thinking!!!

Because it was a Leica 😃

I never got why he hates 35mm focal length so much

@@dominicus9891 I have an irrational dislike of 28mm, so I kind of relate with him on it.

Just wasn't enough time to complain! But trust me, it sucked. :)

The short fange distance means you can adapt pretty much anything to the M-mount.

I agree. I found this method quite brilliant. If I want a niche lens I would definitely go for this.

Actually, the convoluted setting is really annoying, and unneeded. One can set the Sony IBIS FL setting to a button, which brings up a menu that can be scrolled to the correct FL. As far as I know (but feel free to correct me), the FL setting main goal is to tell the IBIS how to compensate. Longer FL need more compensation as a small shake will be magnified. So instead of taking pictures and having a little table, press C2, scroll to the correct FL, press ok and start shooting. This is the SAME process that one uses with manual lenses (without techArt) to make the IBIS perform correctly, so using the TechArt isn't any more cumbersome that normal manual shooting. The biggest limitation is it's 4.5mm helicoid which for longer FL lenses, as shown in the video, the MFD becomes too long, and you need to pre-focus. And with regards to failing a bit near the corners, it's often the case this happens with manual lenses because they are blurry wide open in the corners. It's a lens issue, not adapter issue.

@@fferreres The programming also allows you to burn in the lens focal length in the EXIF if that's important to the photographer. Still a clever way to do it imho.

It is great for someone coming into the Sony ecosystem from another system, but otherwise it is of little use, not when there is a huge range of native E-mount AF lenses.

how was the ea9? is it worthy of upgrade from ea7?

If like me you don't care about the meta data and just want to set the correct focal length for IBIS purposes then I suggest setting the stabilization to manual and setting a shortcut button to manually set the focal length on the camera. its how I do it and it takes only a couple of seconds. Btw I have the LM EA7 and it is not slower than this new version. Only downsides are the size and the battery drain if you keep it attached to your camera overnight. I heard they fixed it in the new version but who knows.

yes i did and it's working great. sadly tho, it won't work on the newer nikon z.

this was kinda available since 2017 or so...

this is why canon and nikon su**s

I'm pretty sure Chris used to teach photography at SAIT but not sure if he still does.

Well, at least the E-mount Voigtlanders have a lever to turn aperture clicks on and off for video use.

It depends of the image quality. When the corners are bad, the sensor cannot detect it's focused. The best combo would be a thin sensor rework on the Sony Alpha

@@maximemasset5297 I feel that the VM50/1.2 has much sharper corners (and center) than the FD50/1.2.

PanaLeica 10-25mm F1.7 and 25-50mm F1.7. Both stunning lenses

@@dpreview micro fourth thirds lenses? I know Chris loves that GH6

Sony have pulled the update as it's causing a lot of problems.

@@richardtargett4128 thank you

Search for Megadap MTZ11

@@Ni5ei Thanks!! I'm surprised that other mounts weren't mentioned in the review. Appreciate the head's up.

@@gerryphilpott9766 It's a different brand and not this same adapter with a different mount. So not really surprising they didn't mention it.

Also Techart TZM-01.

@@vocvoc9895 Yes, Techart also makes a Nikon Z adapter. I only discovered this after I posted my previous response.

The sort of lenses it was made to work with generally don’t have internal focus or floating elements. They're all "unit focusing": they move the entire optical capsule as one "chunk".

@@josephwisniewski3673 I thought it was made for Leica M lenses. Plenty of those have floating elements

@@AManWhoWasntThere Only two out Leica's current 54 M lenses have floating elements. Leica rangefinders only focus down to 65cm, so that mostly negates the need for floating elements. The first lens I had that had them was a Nikon 20m f/2.8 which focused down to 25cm.

@@AManWhoWasntThere yeah most Leica M lenses are definitely not in possession of floating elements. 🤣I love Leica glass, but complicated it isn’t

... it's unit focusing, of course there'll be focus breathing. The longer the focal length, the more noticeable it will be. It depends on the focal length, not on the lens or the adapter. Focus breathing in modern lenses varies because lenses nowadays usually focus by shifting lens groups within the lens, so according to the design they might be able to maintain effective focal length through the focus range. In older lenses (or in a case like this, where the lens as a whole remains unchanged while youre moving it forwards or backwards) focus breathing is literally inevitable and, like I said before, how bad it is depends on the focal length because of perspective.

​@@JeffDvrx ...precisely what we should have seen examples of. How bad etc.

On their website they write: SUPPORTING LENS WEIGHT : 300g for the old version. 500 g new version. So if it works with the first version, it should work better with the new version.

@@juliussternfeld428 that's odd, because the 7 was advertised to support around 750grams... but they did fatigue with heavier lenses and had the wobble.

Yeah, but the aperture setting in the body is not used for anything anyway since it isn't connected to the lenses which don't have Exif support, so why not save on things that costs money and use the aperture wheel on the body to program it with?

I actually think what they did with the apertures is nothing short of genius lol. Also... Blows my mind that someone might find it complicated. Like... If you ever used a microwave oven you should be able to do this 🤣

@@lattesweden Mostly because the whole system is very unintuitive. I have to say that I prefer the Nikon approach there - you could use the camera's f-number setting to put the actual f-number used into the EXIF, for example. Techart's approach doesn't cover all existing M-mount focal lengths, either, and doesn't let you discriminate between, say, a 50mm Summilux and Summicron. I understand that space comes at a hefty premium in their new adapter, but still, the current design is quite user-unfriendly, especially considering that the FL setting is essential for correct IBIS behavior.

@@JeffDvrx It's dumb. Say, if I switch from a 21mm lens to a 135mm prime, I need to spend quite a while rotating the dial, and risk overshooting it (because Sony's interface is kinda crappy in that sense). Oh, and consult their table, or memorize the correct aperture setting for each FL. And then I need to shoot "a couple" of photos, cross my fingers and hope it works? That's bad design, plain and simple.

@@Ildskalli If you do MF with a non Exif lens on Sony you can easy set the focal length for IBIS on the body. But for AF lenses that info gets reported via Exif and the option to set it on the body gets greyed out. Which is how Sony made it and for them this most likely makes sense, the user shouldn't fiddle with IBIS settings on lenses that supports Exif since the user them might change the settings to something that isn't correct. Now this adapter for it to work with AF, needs to pretend to be an adapted AF-lens and then one can't set IBIS focal length on the body since it is greyed out. So they use this kind off cleaver way to set it with the aperture dial on the body which don't do any use anyway.

Are you just getting into photography? It's been like that for so many decades with large lenses that have a tripod mount. The lens stays stationary while the camera moves back and forth to focus.

@@Ni5ei "large lenses on a tripod mount" different than walk around lenses in the video. And no, not of my large lenses do as you describe. They all extend at the end or are internal focus. Are you just getting into photography?
