The added NIC on air-to glass lens surfaces minimizes flare and ghosting, even in challenging shooting situations. The lens employs six elements in six groups optical construction. The lens features a graduated distance scale in meters and feet from 0.3m and 1 feet to infinity. Additional attributes include five iris blades, 74° angle of view and 52mm filter thread.
