I am still working with my copy. I am writing a review so I won’t go into too much detail but I can honestly say it’s a mix of elation and disappointment. Lol. The adapter works well most of the time - or rather the combination of adapter, camera, and lens works well. The problem is that sometimes things get confused. The 31 is actually pretty good on the adapter. The focusing is pretty sure and while not speedy it’s not awful. But I’d say it’s not as fast to use as it is on my k-3 or KP. I use the my adapter on the Sony A7RIII which is my only Full Frame body. The image quality of the 31 is quite good which makes the frustration worthwhile. But comparing the images to my Sony FE 28 is a bit unfair as that lens isn’t the same level of quality within the Sony ecosystem. There are in fact few native fast primes in the 28-31mm range in the Sony FE ecosystem that are at that quality level to compare against. The very large and heavy Sigma Art 28/1.4 is probably the only competing glass which makes the quirks of using the adapter a bit easier to live with.
… this question is probably better asked and answered in the dedicated threads outside this sales thread.
