Olympus E-PL7 has a Micro Four Thirds lens mount and currently there are 132 native lenses available for this mount.
The latest released lenses that are compatible with the E-PL7 are the Brightin Star 60mm f2.8 II, the 7Artisans 50mm f1.2 APS-C and the Pergear 50mm F1.2 APS-C.
E-PL7 also has a sensor based image stabilization system that is up to 3.5-stops effective which means that all of these lenses will be stabilized when used on the E-PL7.
Since Olympus E-PL7 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 E-PL7.
