Nikon Super Integrated Coating is Nikon's term for its multilayer coating of the optical elements in NIKKOR lenses. This multilayer coating helps reduce lens flare (the appearance on the image of the distinctive shape of the lens diaphragm, caused when non-image-forming light enters the lens and hits the camera's sensor) and ghosting (bright spots of reflected light that appear on the image, the result of the camera being pointed at a bright light source). Nikon's Super Integrated Coating is especially effective for lenses with a large number of elements, and the multilayer coating process is tailored to the design of each particular NIKKOR. The number of coatings applied to each lens element is carefully calculated to match the lens type and glass used, and also to assure uniform color balance.
Nano Crystal Coat is an antireflective coating that virtually eliminates internal lens element reflections across a wide range of wavelengths, and is particularly effective in reducing ghost and flare peculiar to ultra-wide-angle lenses. Nano Crystal Coat employs multiple layers of Nikon’s extra-low refractive index coating, which features ultra-fine crystallized particles of nanometer size.
