>>3574252Depends on what focal length you prefer but if you are using the 200-500 as per your pic and still want to shoot FX Nikon, the 300PF is a very good and "light" alternative (753g, 36% of the 200-500's weight, both without collar), it also works pretty well with teleconverters.
For example my Z7, FTZ, 300PF and tripod collar weights 1,807g (pic related).
