Speaking as someone who doesn't need super AF its fine with me - most of my shooting is tripod based and I'd be happy to live with using Nikon F mount to fill in the gaps for now.
Actual user reports on battery life suggest that its not as crap as the CIPA rating suggests.
Can't justify the cost of one anyway currently, especially when the D850 is a shade over £2000 grey!
As a first effort though its pretty darn good, its certainly a helluva lot better than than the A7 / A7r were way back when new.
A7r3 is a mega bit of kit though!
I think it's a pretty good 1st attempt but the a7 MK1 and following were ground breaking, nobody else was doing FF milc.
