Fujifilm X-T100 has a Fujifilm X lens mount and currently there are 88 native lenses available for this mount.
The latest released lenses that are compatible with the X-T100 are the Rokinon 8mm f2.8 Fisheye, the Sigma 23mm F1.4 DC DN C and the Fujifilm XF 8mm F3.5 WR.
Fujifilm X-T100 doesn't have a sensor based image stabilization system but 19 of these lenses already comes with optical image stabilization.
Since Fujifilm X-T100 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-T100.
