OM System M.Zuiko Digital ED 75mm F1.8 lens 

Characterized by its telephoto design and bright maximum aperture, the black M.Zuiko Digital ED 75mm f/1.8 from Olympus is a 150mm equivalent prime for Micro Four Thirds mirrorless cameras. Coupled with the reach and visual compression of the focal length, the bright f/1.8 maximum aperture enables great control over depth of field to make this lens ideal for portraiture. Its optical design incorporates three extra-low dispersion elements,reducing a variety of aberrations and color fringing for sharp, clear, and accurate colour imagery. A ZERO coating has also been applied to individual elements to suppress surface reflections and flare for greater contrast and color fidelity in a variety of lighting conditions. This lens is also a wonderful match for movies as well as stills. A superb fast autofocus system;quick, quiet, and precise.
