The M.Zuiko Digital ED 60mm f/2.8 Macro from Olympus is a 120mm equivalent prime for Micro Four Thirds mirrorless cameras. A Focus Limit Switch can also be used to better facilitate working at close or distant ranges by constraining the focusing mechanism for faster, more precise AF. In regard to the optical design, extra-low dispersion and high refractive index glasses are used to control a variety of aberrations and a ZERO coating has been applied to suppress flare and ghosting to improve contrast and color accuracy.
