Best camera for the nikon af s dx 18 300mm f 3 5 6 3g ed vr?
This lens is made for APS-C, so I'd start with an APS-C Nikon. My pick is the Nikon D7500. It's a sensible all-rounder that pairs well with a travel superzoom, and it's the one I'd choose if I wanted a single body for a trip.
If you shoot fast action, the Nikon D500 is the more capable tool, though it costs more. On a tighter budget, the Nikon D3500 takes the same lens for less money.
You can also mount it on a full-frame body like the Nikon D850, but the camera switches to APS-C crop mode and you lose resolution. I'd only do that if you already own the full-frame camera. The lens page has the full list of compatible bodies.
