Fujifilm X-T2 has a Fujifilm X lens mount and currently there are 84 native lenses available for this mount.
The latest released lenses that are compatible with the X-T2 are the Rokinon 8mm f2.8 Fisheye, the Fujifilm XF 8mm F3.5 WR and the Tamron 11-20mm F2.8 Di III-A.
Fujifilm X-T2 doesn't have a sensor based image stabilization system but 18 of these lenses already comes with optical image stabilization.
Since Fujifilm X-T2 has a APS-C sensor, it has a focal length multiplier of 1.5x 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 X-T2.
