I know the answer seems a bit silly, at first, but here's my situation. I have the Z6ii ( it replaced my D7200) but all my lenses are F-mount. I shoot mainly wildlife so my 200-500 is my go to lense, that and the Tamron 70-200 G2 (fantastic piece of glass).
I would like to get away from using the FTZ adapter so I am thinking about getting the new Z 100-400.
My question... should I spend the money on new glass or should I get a D850 so I can keep the glass I already have?
