I’m on the cusp of buying one - currently selling off my Canon gear.
looking forward to it. Let us know how you find it
Anything you want to know, had mine since they were available in China.
I mostly got it for the AF and I didn't want the increased size of the later A7 bodies.
It keeps up perfectly with my 3 year old and 9 month old.
I have mine set so the shutter button does AF-S for static subjects.
The back button is then set to do AF-C with eye tracking for the children. Perfect setup for me, instant access to both focusing methods.
I use electronic shutter 99% of the time as well, coming from the A7R with its clunky shutter it's so nice.
