>>3418335If you want to use your F-mount lenses (with the FTZ adapter) and EN-EL15 batteries, get a Z6, right now it's pretty much the best non-pro video camera; you would have to buy XQD cards though.
The new Z-mount lenses are great (for both stills and video) and the awesome 24-70 f/4 S is "only" ~$600 if you get it as a kit.
Nikon also just announced a Z6 Filmmaker's Kit for $4,000 (roughly $650 off):
