Leica TL has a Leica TL lens mount and currently there are 52 native lenses available for this mount.
Leica TL doesn't have a sensor based image stabilization system but 8 of these lenses already comes with optical image stabilization.
Since Leica TL 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 TL.
