Nikon

Nikon's current system is the Z mount: full-frame bodies such as the Z8 and Z6 III, and DX (APS-C) bodies such as the Z50 II. Nikkor Z lenses cover everything from the Z 50mm f/1.8 S to the Z 70-200mm f/2.8 VR S and the Z 180-600mm for wildlife.

The F mount is the DSLR system. F-mount lenses can be used on Z bodies with the FTZ II adapter, which makes the move to mirrorless gradual.

For those who want reach without changing lenses, the Coolpix P950 and P1100 are superzoom bridge cameras, with the P1100 reaching 125x optical zoom.
