Silent Wave Motor AF-S NIKKOR lenses feature Nikon’s Silent Wave Motor (SWM), which represents a significant advance in AF lens technology. SWM uses ultrasonic vibrations—rather than a gear system—to focus the lens, providing incredibly smooth, silent and precise autofocus operation.
Nano Crystal Coat
An anti-reflective coating developed by Nikon that virtually eliminates internal lens element reflections across a wide range of wavelengths. Nano Crystal Coat solves ghost effects caused by red light and effectively reduces ghost and flare caused by light entering the lens diagonally.
ED (Extra-Low Dispersion) Glass
An optical glass developed by Nikon that is used with normal optical glass in telephoto lenses to obtain optimum correction of chromatic aberrations.
AS stands for Aspherical lens elements. This type of lens utilizes non-spherical surfaces on either one or both sides of the glass in order to eliminate certain types of lens aberration.
M/A Select NIKKOR lenses have a focusing mode which allows switching from automatic to manual focusing with virtually no lag time by simply turning the focusing ring on the lens. This makes it possible to seamlessly switch to fine manual focusing while looking through the viewfinder.
IF Lens A NIKKOR lens in which only the internal lens group shifts during focusing. Thus, IF NIKKORS do not change in size during AF operation, allowing for compact, lightweight lenses capable of closer focusing distances. These lenses will be designated with the abbreviation IF on the lens barrel.
