Nikon D1X has a Nikon F lens mount and currently there are 304 native lenses available for this mount.
Nikon D1X doesn't have a sensor based image stabilization system but 101 of these lenses already comes with optical image stabilization.
Since Nikon D1X has a APS-C sensor, it has a focal length multiplier of 1.5× so you have to multiply lenses original focal length with this multiplier to find the Full Frame equivalent focal length of the lens when mounted on D1X.
