Yes i had an A6000 and a nex7 (also nex-5n now that body was frustrating with only one dial)
While its less than optimal i can make do with two dials even if they are both thumb dials.
I rarely/never used the exposure lock or the AF/MF (I used switch it on the lens though my current lenses lack it).
So overall I am happy with it, first impressions below....
Initial impressions:
while the body is compact its slightly fatter than I expected. not the end of the world but if they gave IBIS a miss for another 100g I would have been happier.
My expectation was such a body was rather low in that a good sensor with the latest AF and this satisfies that.
I am liking the flippy screen and the AF seems to be the best for A7-class i.e. not including A9-class bodies. certainly seems better and touch more reliable than my A7RIV.
The EVF will take some getting used to especially having used the huge 5.6millon dot EVF on the A7RIV. this one really feels like a peep hole!
ergonomics wise I always liked my A6000 apart from lack of forefinger dial so i like this too. less buttons but I like the minimalistic approach. you can reassign the movie button too which is really useful for me as mostly a stills shooter.
the most annoying part of all is can't find a screen protector for the LCD
