What parameters are you using? Aperture? Focus points? IBIS? AF-C, S? etc.I've tried both AF-C & AF-S, but mostly used AF-C so far. Wide focus, various apertures, no IBIS (A6300). I took it out this morning in bright light and it had the same problems. I'd be happy to discover it's something I'm doing wrong, because its performance on the TAP is vastly inferior to all the other lenses I've tested.
I just tried it on my a6300 with Phase Detection AF, Center Focus Area, AF-C, lens set to f/5.6 and to infinity, a6300 in Aperture mode and F/2.0.
Position camera so that focus point is on contrasty spot. This seems to work for me.

Same here, I have never had a problem using this lens with TAP . . .

Last week I picked up some Voigtlander m-mount lenses to use with the TAP. The 40 1.4 works great, but the 15 4.5 constantly hunts and often fails to find focus. Not really a big deal, I guess, since MF isn't a problem with this lens, but I was expecting the ultra wide focal length to be super snappy, so I'm a little disappointed.What parameters are you using?

I wonder if AF performance with an ultra-wide lens would be better with the central or flexible spot focus area rather than wide. Also I recall Guy pointing out that on Sony cameras AF works best when the focus point is on vertical rather than horizontal lines.

Emailed Teacart Pro about the wobble in my adapter. Still have not yet heard back from them.

Can you describe the "wobble" you are referring to? I've always had a" wobble" on my adapter since day 1 and I assumed it was normal.
Let me describe my wobble: I am referring to the movement of the silver mount as it moves in and out of its black housing. I understand that the mount should only move in and out, however, my copy has up and down (tilt?) movement.
This is only noticeable if I touch (or gently wiggle) the lens while it's mounted on the TechArt Adapter.

This is the same problem I had also, your description is similar to what I was experiencing.
I was able to loose critical wide open focus on some lenses because of this wobble. Even if I touched gently the lens, it was able to wobble up and down. This was with a very light weight lens too (Zeiss 50mm f1.5 ZM).
I have since bought a spare adapter I'm using, while my other one was sent to Hong Kong under warranty.
This second TAP I have has no wobble.

Thank you for the suggestions genji and k-h.a.w. I have tried center focus but not flexible spot. Either way, this is the only lens I've tested where performance has been less than optimal, so I'm still quite pleased with the performance of the TAP.

Just heard back from Teacart after sending them a video of the "wobble" in the adapter. On my own dime I will send it to Hong Kong for replacement. I will probably purchase another one to use in the meantime, and when they send me the new one, I'll have a spare. So it goes.

I'm having a problem with the TAP inconsistently focusing the ZM 35 1.4 on my A7Rii. Sometimes it does but more often it doesn't. Any suggestions?

Set to small aperture? It fucusses better at wide apertures.
Off centre focus point? It focuses better with centre point
Low light? Focuses better with plenty of light.
What you should do is try bright light centre focus f2. Assuming that's good (if it's not something is wrong) carefully test the other variables (try progressively off centre points at f2, then go centre for f2.8, then off centre, then f4) until you strike inconsistent results. Then you will know under what conditions you can rely on consistent results.

If anyone was wondering (I know I was) the TAP works fine with the A6500, and you can use the touchscreen to select where you want it to focus. Between the technology in this camera and adapter, I can't help but be amazed by the fact that I can have AF, stabilization, and touch capabalities with lenses that were released decades ago.

Good point. It's reassuring to know that our TAP will potentially get even better as new functionality and CDAF speed gets upgraded in future models.

Also try to set focus on vertical (rather than horizontal) lines. And perhaps switch to flexible focus-M.

Did you experience light leaking near the wobble?

I would be happy if CDAF was more reliable across the frame.
