Samsung NX500 has a Samsung NX lens mount and currently there are 34 native lenses available for this mount.
The latest released lenses that are compatible with the NX500 are the Samyang 14mm F2.8, the Rokinon 14mm f2.8 and the Rokinon 24mm f1.4.
Samsung NX500 doesn't have a sensor based image stabilization system but 7 of these lenses already comes with optical image stabilization.
Since Samsung NX500 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 NX500.
