Panasonic L10 has a Four Thirds lens mount and currently there are 47 native lenses available for this mount.
The latest released lenses that are compatible with the L10 are the Venus 33mm F0.95 CF APO, the Samyang 135mm F2.0 ED UMC and the Samyang 300mm f6.3.
Panasonic L10 doesn't have a sensor based image stabilization system but
3 of these lenses already comes with optical image stabilization.
Since Panasonic L10 has a Four Thirds sensor, it has a focal length multiplier of 2× 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 L10.
