Leica SL2 has a Leica L lens mount and currently there are 66 native lenses available for this mount.
The latest released lenses that are compatible with the SL2 are the Sigma 14mm F1.4 DG DN, the Sigma 17mm F4 DG DN C and the Sigma 50mm F2 DG DN C.
SL2 also has a sensor based image stabilization system that is up to 5.5-stops effective which means that all of these lenses will be stabilized when used on the SL2.
Since Leica SL2 has a Full frame sensor, it has a focal length multiplier of 1× so lenses will provide their original focal length on SL2.
