The adapter seems to have some difficulty recovering from really out of focus shots. For example, if you focus on a white wall, the adapter would extend and get confused because everything turns into a blur. Now if you try to focus on something else, the adapter would appear “frozen”. Normally with native lenses, the focus unit would rack back and forth in an attempt to find something to focus on, but that is not the case with the TZM-02. To make the adapter work again you have to find something with really strong contrast or a subject near the focal plane. This is a huge departure from the usual behavior and sometimes made me wonder if the adapter is broken. This appears a lot more often with AF-S and smaller AF boxes and less with AF-C and Wide-L. I suppose with the latter setting it is easier to catch something with enough contrast inside the box to make the adapter recover.
The AF is definitely faster and more accurate with less hesitation compared to the 1st generation, so in good lights and subjects with lots of contrasts it does work very well. This one was taken with the VM40/1.2:

Does it use the same USB adapter as previous Techart adapter?
If you connect it to USB3 port on a computer, does the computer has any problem recognizing the adapter?
On older version, I pretty much needs computer with USB-2 port like my old laptop to update any firmware
as connecting it to USB-3 port usually does not work. I pretty much decided to give up on Techart
and won't buy anything from them again until they resolve this issue.
I can't get it to recognize the USB dock on any of my laptop's USB3 port, so I guess it is still the case. Firmware update is always a huge hassle with all Techart products and I don't get why they don't just use a simple file copy method like Megadap or Fringer. The USB dock is also still using a micro-USB port instead of USB-C like it should in 2023.
