Just got this lens for my A6400. Don’t normally believe all the reviews, but after half a day at the zoo and almost 800 shots, it is really sharp!! AF was spot-on and stayed on the focus point. AF is also fast to connect on the subject. Granted, it was a partly sunny to sunny day, but I was more than satisfied with its performance. Animals wete always moving, particularly the birds. It tracked all of the animals really well.

How is the AF in low light/night conditions?

I’m going to test that this weekend and I’ll let you know.

A very interesting lens indeed. How do you like its edge performance at wide angle (18mm) ? Reviews suggest that this might be a weak spot, reducing the lens' versatility for landscape shots.

Well, any results?

Good to read that! I compared my copy with my 18-135 and at 300mm my copy was quite soft, compared to the very sharp 135mm on the other lens, so I decided to keep the much much smaller and lighter 18-135 and crop at the long end if needed, with not much worse results.
