I bought an A7II. AWB does not work really. Ergonomics is shit, none of the buttons or dials are where your fingers are, but I got it with the battery grip and that makes it ok, it gives a very tight grip on the camera. It's a very small camera as is.
IBIS is very good, much better than I expected, takes out the micro jitters in video and I can handhold 1/2 seconds on a short lens.
Autofocus is ok, works like on a late stage dslr.

The camera is small and looks cool with the grip on, like very solid. I don't expect anything to break. Adjusted the evf sensor with an electric tape hack I found online. Pretty happy so far.

Don't pay much for this generation, but it works well if you mostly take pictures of static subjects.
