Agree on the CV 28/2. For some reason, this one only focuses well at center.
Another vote for the 50/1 Noct. The Voigtlander 50/1.5 Heliar and Leica 50/1.4 Lux work great too.

I ordered Aug 18th now Sept 26th still nothing. I also emailed Techart and never heard back from them. Not a good sign to buy again from them.
I ordered it August 14th from B&H and never heard anything so it's all the same! How many did Techart make ? 50!?!?!

Any takeaways from using the CV 50/1.2?
I thought it performed well on my A7R3. It does not lock focus if the focusing point (M) is at the very edge of PDAF area but it works away from center as well.
For all those waiting - I think I just got a shipping notice from Fedex.... unless there's some other item of camera gear I've ordered and forgotten about.... which is admittedly a possibility.

I'm using it with a A7IV, Minolta 58mm 1.4, Minolta 55mm 1.7, Minolta 45mm F2, and canon 50mm 1.4 LTM (Japanese Summilux) they all work well.
With the Minolta lenses, how far off center can you:
1) Focus at all in AF-C with focus lock and take a picture?
2) Get the correct focus?
I ask since I have found several lenses (Minolta + M42) that confirms focus outside the middle 1/3 box on such a grid and allows me to take an image, but then when I check the sharpness in Playback it turns out it front focused.
(within the middle 1/3 box focus is correct).
I have 2 major thoughts for those using the new TAP.
1) It works much much better on an a7iv than the a7c. I was not getting the results that some of you were reporting and/or indicating (though it's subjective with what working "good" means, and what lenses are used).
Used the a7iv and a7c with the new TAP using the 35/2 Ultron and 50 Sypotic, both in AF-C, Eye-AF (Human) with Expanded Flexible Spot, Wide or Center and with "AF Tracking Sensitivity: 3 (standard)."
The A7iv was considerably better in all regards--quicker to acquire the subject, quicker to lock once found(go green), racked back and fourth between near and far subjects faster and very little fluttering comparatively. The CV 35/2 is poor on the a7c, but would be quite usable/not near as crippled on the a7iv. The Syoptic is quite good on the a7c (like the 4 other fast 50mm's I have used) and another level on the a7iv. The a7iv allowed for great AF and tracking outside the dead middle of the frame as well. For serious TAP users, the a7iv is real consideration.
2) On the a7c, the "AF Tracking Sensitivity" in the menu makes a large difference. And its lens dependent. I can barely get the a7c to lock onto a static decently contrasty subject in normal light with a couple lenses, but changing the "AF Tracking Sensitivity" greatly reduced the fluttering, and decreasing the actual time to lock and go green. That setting makes a very appreciable difference on nearly all my lenses I've tried.
I'm having....I'd say pretty good results with my a7c and most all my Leica lenses, new and vintage and CV's (50/1.2 and 75/1.5) so reading the above post makes me want to grab an a7IV...

So you are saying that once you set "AF Tracking Sensitivity" higher, a7c was better?
I can only focus in the center area. The edges won't focus. But I have the same issue with my MC-11 adapter and some Canon lenses. Must stay in the center and a bit off from the center. It does work well in AF-C all AF-C functions perform well. Focus depends on lighting. In low light it will struggle but with enough light its not a problem.
