Can I adapt the nikon af s 85mm f 1 4g to nikon z?
I can't confirm that from the site. The Nikon AF-S 85mm f/1.4G page lists it for the Nikon F mount, and every camera it's paired with there is a DSLR. None of the Nikon Z bodies appear on that page, so I won't tell you it fits.
The Lenses page says mirrorless mounts are shallow, which makes adapting old manual-focus film lenses easy and cheap. It doesn't cover autofocus lenses on Z bodies, though. Before you buy, check the adapter's own compatibility details for this lens and your specific Z camera.
If you're mainly shooting people, the portraits guide explains why an 85mm works so well for them.
