It seems Nikon has introduced the Z-mount for its mirrorless cameras, and you have an adapter to go from Z to the F-series mount for older lenses. There will be Z-mount lenses specifically designed for mirrorless, but there might also be lenses (especially from third parties) that use an old design, and just modify the mount so it fits on mirrorless cameras without the need for an adapter.
