This large aperture lens becomes a medium telephoto lens offering 100mm equivalent angle of view on Four Thirds cameras. The optimum optical design and molded glass aspherical lens elements provide excellent correction of coma aberration. It ensures superior peripheral brightness and provides sharp, high contrast images even at the maximum aperture. The Super Multi Layer Coating reduces flare and ghosting. Superior optical performance is ensured throughout the focusing range. The rounded 9 blades diaphragm creates an attractive blur. This lens incorporates HSM (Hyper Sonic Motor), ensuring a quiet and high speed AF as well as full time manual focusing capability.
