A versatile and relatively compact telephoto zoom, the M.Zuiko Digital ED 75-300mm f/4.8-6.7 II from OM System is a 150-600mm equivalent lens for Micro Four Thirds mirrorless cameras. The optical design makes use of three low dispersion elements and three high refractive index elements to control both chromatic and spherical aberrations for a high degree of clarity and sharpness throughout the zoom range. A ZERO coating has also been applied to help reduce lens flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions. Additionally, this lens utilizes a Movie & Stills Compatible AF system to achieve smooth, fast, and near-silent focusing performance to benefit both photo and movie applications.
