Anyone here has any experience working with Techart support? I have an almost brand new ta-ga 3 adapter. It worked for a week and then stopped working. It seems the motor driven screw used for af cannot drive the focusing screw. I mailed their support mailbox but they ignored me. Pls help!! Thanks!
Based on what I've read here, they can be pretty pokey about responding, FWIW.

Yep, their support is dismal. My impression has been that you might be more successful contacting them via their Facebook page (though I have no first hand experience with this since I don’t use Facebook).
I have one since almost six months and for now nothing negative to report (crossing my fingers of course).
Have even used it with a quite heavy C/Y Distagon 35 F1.4 without any particular issues.
Of course I'm discounting the fact that when it will quit working it will be for good, according to all the experiences reported here with their support..
Okay. I am reaching out to the reseller to see if he is willing to give me a replacement. Love the adapter, when it works.
I guess the problem that i have boils down to mechanical design. The screw (adapter) that drives the focus screw (lens) either has too much torque or cannot get a good hold of the focus screw. When this happens, even the manual focus wheel stops working. It turns emptily. I probably push somewhere too hard when switching lens. But this is what, after using it for one week? Lol ...
Unfortunately this seems a common problem with adapting Contax G lenses, even with manual focus adaptors. The coupling of the focus mechanism at every lens change looks clunky enough to have dissuaded me from going that route..

Yes, absolutely. They have their quirks but it is a wonderful product.
Totally agree. The TAP reminds me of the poem by Henry Wadsworth Longfellow:
"And when she was good, she was very, very good,
But when she was bad she was horrid."
If you can accept its limitations, and pair it with the right lens(es), it can deliver excellent results. Up until now I've used it with relatively small, light lenses: C-Sonnar ZM 50/1.5, M-Hexanon 50/2, Tessar C/Y 45/2.8, Rokkor MD 45/2, Nikkor-H.C 50/2, and a Planar G 45/2 (converted to M-mount by FM member, sebboh, because I found the TA-GA3 too flaky and frustrating). But I just picked up a Planar ZF 50/1.4, which is bigger and heavier than I normally use with the TAP, in an attempt to create an autofocus version of my much-loved Planar ZE 50/1.4.
Yeah, small and nimble lenses is where the TAP is at home, in fact I've shaved all the heavier vintage lenses that I used to own and trying slowly to substitute them where possible with small and light rangefinder counterparts.
The Summilux 35 1.4 ASPH is only 320g, so it will work like a charm on the TAP, max supported weight is 700g (including any further LM adapter). My C/Y Distagon 35 1.4 was more than 600g alone, plus the adapter was really on the verge for the TAP (being even quite bulky per se).
I think that if a lens suffers from focus shift, you do not stop down at the desired aperture before focusing with the TAP, you should still get the shift no? and it could be of course an issue because when the light gets dim, it becomes increasignly difficult for the TAP to focus, especially off-center (my experience is that above F4 it usually struggles in dim light outside of the center zone).
For me it works good enough, provided that your expectations are not of anything that focuses super fast and super-consistently in low light.
My experience is that it works quite realiably in the center part of the frame even with the lens stopped down, but as soon as you move the cursor towards the rule of thirds zone, it has an hard time locking focus with anything above F4, so I usually tend to focus and recompose when I use it.
Eye-AF seems to work, although even here success rate will be significantly light-dependant.
Tracking of course remains a no-go, it's just simply too slow to focus.

Excellent summary that matches my own experience. I was initially skeptical about v6 and the series III bodies but I've changed my mind.
I RECENTLY BOUGHT CONTAX 90MM, I HAVE ALREADY OWN TECHPRO.
INITIALLY THINK THAT BUYING C/Y - LEICA M FITS, BUT IT IS NOT.
CAN SOMEONE PLS HELP, WHAT ADAPTOR TO BUY
IN ORDER TO MOUNT THE CONTAX 90MM TO AN ADAPTER - LEICA M -(( TECHART PRO.))
PLS HELP.

If you bought a Contax G-mount, I'm not aware of an adapter that converts to Leica-M.
The G-mount Contax lenses are different than the C/Y. There was/is a Techart AF adapter for G-mount lenses but I don't know if it is still sold, or was as well-received.
