Here's a link to the Pronto II manual for those interested. The Fn button on the adapter is a nice add vs Techart. There are three modes. AF Mode which is how the adapter ships. It is the normal AF position. Press the Fn button once, the adapter moves into MF mode. Press the Fn button again, the adapter moves into Macro MF mode where the adapter will full extend. Press the Fn button for 3 seconds returns the adapter to normal AF mode.

The process to have the adapter record lens focal length is similar if not identical to the Techart adapter.

Does eye focus work? The website only mentions face focus. I'm also amazed that they don't have a rubber cover for the USB port. They mention the battery drain problem in the 'notes' and removing and reinserting the battery as a fix. Weird that they didn't fix the problem or these are simply notes copy/pasted from the original version.


Here's a quick test of eye AF in animal mode. Notice that Nora is in the shadows but animal eye AF worked pretty well. More testing needed but encouraging.

Hi, I just bought a second-hand Techart pro and my A7rii doesn't recognize it although my seller insisted that it worked on his camera. Before trying to return, I just want to ask. If I attach the adapter without the lens onto the camera, will the camera recognize the adapter? (Currently I don't have a lens in hand)

Thank you.

As far as I know it should, since the lens you mount on the TAP doesn't have any kind of contact and way to communicate with the camera through the adapter.

Do you have the possibility to try it out on a friend's camera or in a friendly shop maybe?

Hi, thank you. Unfortunately, my town doesn't have a brick-and-mortar shop nearby. And all of my friends use Fujifilm cameras.

I just checked with my A7R4 and the adapter is recognised without a lens attached. The lens version shows in the menu as the firmware version e.g. 06 or 07. It will be no different with the A7R2.

Thank you very much!

Today I also tried with a A7r4 from a local guy I found on Facebook but it also didn't get recognized by the camera.

So I disassembled the device because I was curious and I cannot return it (long story short, I learned my lesson in buying online...).

I have no background in electrics so I don't know what to do to find out where is the memory chip and try to flash directly into the chip.

But anyway, inside the adapter, they use tons of glue and some flimsy wires. I feel like with $300-ish adapter, it should have had a better construction. Therefore, I will skip buying another Techart adapter.

I'm not sure if the Fotodiox adapter is better in this regard.
I'd appreciate it if anyone who has tried to disassemble the Fotodiox adapter tells me about its build quality.

In your situation, I’d consider the Fotodiox Pronto II that Bob (rji2goleez) describes in detail a few posts back.

I will consider it when my wife forgets that I bought a similar one. :-D

Thank you.

P/s: hopefully at that time there's a local reseller so that I can get the warranty easier.

If you paid with PayPal (or anyway with a credit card) I guess that if you didn't disassemble it you would have been able to get your money back somehow even with no accepted returns, by proving that the product you received was defective (what an ass of a seller you found, sorry for you pal).

But guess that now that you've played the little technician it's too late..

Well, I consider the TechArt Pro adapter a consumable, just like soap or toilet paper.

Some time ago, I was fortuned and lucky enough to have had the chance to acquire a secondhand Leica Noctilux 50mm f0.95 at an unbelievable good price. A dream of more than 10 years worth of waiting for such an opportunity that didn't come soon enough

I personally don't own a Leica body and have exclusively been using the lens (very successfully) with my trusted Sony a7RIV, albeit the weight imbalance and obvious difficulty in acquiring proper focus consistently.

Recently I purchased the TechArt Leica-M adapter, a definitely under-engineered product and prone to mechanical failure as we all-too-well unfortunately already know. But it's convenience of use has proven to be a lifesaver for lots of situation for me.

I've developed a simple technique to use it, which is to instead of holding the camera while letting the adapter normally do it's work on the lens, I actually just hold the lens itself and let the adapter move the camera body, which is a much lighter load. With some practice (and lots of patience) I have managed to make this setup work very well in hopes that will mitigate the appearance of the wobble issue, to as late as possible. Focusing works fairly well and I am satisfied with the hit ratio (which by any means and realistically is bad given the characteristics of the lens). But it does the job well enough, mostly better than when I try to focus manually myself for extended periods of time.

What I cannot understand, is how companies like TechArt can survive throughout the years with such bad ratings and reputation, making products that are consistently mediocre. On a side note, I also own another TechArt adapter for the GFX/EF mount and that has equally given me nothing but troubles since the first day as well.

My question is, how on earth this Leica-M/Sony adapter now that its more than five years old, was never cared for to be improved or the design somehow changed for increased and acceptable long-term reliability?

Just out of curiosity, who are these people? Where are they based at and who is their development team? For me its always been awe, companies that manage to survive years making premium-priced products with less than average performance or endurance, that never reply to their customers or take them into consideration, and that still manage to stay afloat selling the same items for more than half a decade long that have never worked properly since the first day. Quite an incredible feat!

Either way, my post is mainly to share how I am using the TechArt in hopes others with the same adapter (still working well or already not in prime mechanical condition), can try to take the most advantage of it. Either handheld or on a tripod (by obviously mounting the lens itself on the support gear), you will potentially extend the life of your TechArt adapter by easing the force with which it needs to do it's work. Though not a perfect solution nor convenient all the time, I find that holding the lens and just letting the adapter freely move the body, is a sure way to hope for a little bit of a longer worry free operation.

Cheers, Travis

Hi,
I have one burning question. I know the pronto AF doesnt work for video, but does the focal length metadata work in video?

I don’t do much video so I really don’t know. I’ll try to get some to try it out.

Thanks. if it does, that might be the only way to do Gyro Stabilization ( which requires focal length metadata in catalyst browse) for legacy lenses.

Thanks. I have successfully used that technic too for very heavy lenses and a second adapter attached as well.

..hi all,i've got the TAP from some years and i using it on A6500 with many vintage lenses, i'm almost happy,but i've a little problem,it doesn't focus sharply with a Trioplan 50/2.8 (Exa Mount) wide open, i tested another Trioplan on the same EXA>LM adapter and i try some other adapters,but i get the same result,it doesn't focus sharply, i try some other lenses,E.Ludwig Meritar 50/2.9 and MOG Primotar 50/2.8 ,but in those case,it works well,Trioplan when is stopped down a bit (F/4) it focus well,some other one had this issue?And how fix it,if it's possible?
