Can I use adapted lenses on the nikon z6 iii?
I don't cover adapters on this site, so I can't tell you how adapted lenses behave on the Z6 III. The camera's Nikon Z6 III page lists the lenses I've catalogued for it, and it's the best place to start. Almost all of them are native Nikon Z or Z-mount third-party lenses, from the Nikon Z 24-70mm f/2.8 S II to the Nikon Z 85mm f/1.8 S and the Viltrox AF 35mm f/1.2 LAB.
If you want a sensible everyday kit, I'd pick one zoom, one fast prime and one wide lens from that list. The mount page explains why buying into the Z mount makes sense over several bodies.
