Developed by Nikon optical designers and Nikon glass
specialists, ED (Extra-low Dispersion) glass used in selected telephoto and
telephoto Zoom lenses provides superior performance.
ED glass effectively
minimizes Chromatic aberration to a degree that is remarkable in telephoto
lenses. Advances such as this, backed by a great amount of valuable data
gathered through the long years of Nikon’s association with professional
photographers, as well as through intensive R&D, ensure that Nikon continues
to make lenses that meet or exceed market needs
