Tool the X-T2 out again on the weekend. While it still has lovely iq, you really get used to the flexibility of the files from the A7R3...
I think I've had the A7R3 long enough at this point to say 2 things definitively, in terms of my experience between Fuji and Sony...
1) Shooting on the Sony is miserable. I feel like I can't see the entire EVF because of the small/close to the body eyecup and I feel like half the time I'm shooting blind and hoping for good results. Fuji felt like I was in total creative control with the physical dials and amazing EVF/deep eyecup on the H1.
2) Fuji files can't hold any sort of candle to the Sony files. In fact, no files that I've seen yet can hold a candle to Sony files. ARWs are raw putty in the hands, incredible dynamic range, incredible recoverability, and the 42mp lets you crop so deeply without major quality loss. ARWs are pure bliss to edit, even if they take a little more time to edit, because the possibilities of what you can do to them is so much greater than any other brand I've worked with. The fact that Lightroom plays very nicely with ARWs is a huge win for me as well vs Fuji.
Point 2 alone is enough to keep me in the Sony camp for now. I just wish the actual photo creation portion of shooting Sony was a better experience.
A side note...did a single (very dim) light source, pitch dark room photo set at ISO 12800 (intentionally) and the results are AMAZING. Fuji just can't do it. That's what I love most about the Sony, the raw hardware opens up new, exciting opportunities for photos I can't get from other brands even if the actual shooting isn't all that fun.
