Nikon AF-S NIKKOR 14-24mm f/2.8G ED Zoom Lens

With a fast fixed maximum aperture of f/2.8, the Nikon AF-S NIKKOR 14–24mm f/2.8G ED lens's exclusive lens technologies and innovations in optical design deliver outstanding sharpness, color and contrast, even in backlit conditions.

The fast, ultra-wide-angle AF-S Zoom-NIKKOR 14–24mm f/2.8G ED is optimized for edge-to-edge sharpness on both FX- and DX-format Nikon D-SLR cameras.

The AF-S Zoom NIKKOR 14–24mm f/2.8G ED's rugged construction and professional-grade dust and moisture resistance withstand even the most trying conditions. Nikon's exclusive Silent Wave Motor (SWM) and Internal Focusing (IF) technologies enable ultra high-speed autofocusing with exceptional accuracy and powerful, super-quiet operation. Nano Crystal Coat (N) minimizes ghosting and flare, and Aspherical Lens Elements (AS) virtually eliminates coma and other types of aberration—even when used at the largest apertures.

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 Disepersion) 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.

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.
