Techart Pro test with Samyang 135mm (A7ii)

I repeated this test again, but this time on A7ii since the IBIS of the camera can help me to shoot more precisely.

When I used the AF function, it's not much difference between pre-coarse adjustment or not but in pixel-peeping level, some quality degradation can be seen. However, it's very negligible and can't be recognized by normal view.
