I never expected to own three bodies but I have ended up with a Z6ii, Z7ii and Z9. The Z6ii is a wonderful low light camera that is a great for events and studio portrait works. Skin tones with S glass are beautiful. This replaced a D750. The Z7ii has the resolution and lightweight to be a nearly perfect landscape camera. I replaced a D850 that I kept for wildlife work until the Z9 arrived. The Z9 is the best action/sports camera I have ever used. Faster than my D5, better subject tracking than my D850 and perfect ergonomics for my hands. I have no experience with the D500 but cropping the D850 images was a similar, very good experience for wildlife.
