The focus tracking of this A7V and 40mm is incredible. In this shot she's running around me and changing direction fast, so both of us are moving and I've also got the camera down low (using the rear screen extended out), whilst trying to keep my balance and the camera still performs with every photo having perfect eye-AF. I would have struggled with the D810.
I've been playing around with lots of new free LR filters, there are some very nice ones, but I find a lot of them ruin the dynamic range. So, it's often a toss up between going down the more "arty" route or keeping it truer to real life. The latter seemed better in this case as her white fur parts can blow.
