Canon M6 has a Canon EF-M lens mount and currently there are 20 native lenses available for this mount.
Canon M6 doesn't have a sensor based image stabilization system but 4 of these lenses already comes with optical image stabilization.
Since Canon M6 has a APS-C sensor, it has a focal length multiplier of 1.6x 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 M6.
