To ensure superior picture quality at all subject distances from macro to infinity, a host of state-of-the-art, Nikon original optical features and technologies are incorporated. Internal Focusing (IF) design allows faster, smoother autofocusing. Two aspherical lenses are employed to correct spherical aberration and coma. The incorporation of a Nikon’s exclusive Nano Crystal Coat dramatically reduces ghosting and flare caused by internal reflections. An additional ED glass element minimizes chromatic aberration to deliver higher resolution, high-contrast images. All of these factors contribute to the extremely accurate image reproduction capability of the AF-S Micro NIKKOR 60mm f/2.8G ED.
