My Hybrid Camera Setup (Sony a7RV) 

A7RV, that is the camera I need. I have heard this in my mind a lot of times. There a lot of APSC vert affordable lenses, it's worth considering something like the FX30 or a6700. You can probably get 2 of these plus APSC lenses and still save money. 4k 60 all modes and 26Megapixel sensor, also custom luts and same Slog advanced mode of the FX6 in the FX30.

If you don't need the Flippy screen, the A1 would give you 50MP stills & 4K 50p with no crop
