    Nikon AF-S NIKKOR 14-24mm f/2.8G ED Zoom Lens - Press Release
    Nikon introduces new ultra-wideangle, high-speed zoom NIKKOR lens

    Tokyo – Nikon Corporation is pleased to announce the introduction of the new AF-S Zoom-NIKKOR lens with the world’s first 14 mm focal length for f/2.8 to further strengthen its zoom lens lineup. This new wideangle lens, together with the simultaneously introduced medium-range AF-S NIKKOR 24-70mm f/2.8G ED, and the existing AF-S Zoom-Nikkor VR 70-200mm f/2.8G IF-ED telephoto zoom lens, is part of an exclusive Nikon high-performance zoom lens system featuring the high f/2.8 aperture and covering a focal range of 14 mm to 200 mm.

    This new zoom lens offers a full range of professional features to provide superior overall performance. In addition to the fast maximum aperture of f/2.8 at all focal lengths, it features a short closest-focusing distance of 0.28 m/0.9 ft. with focal length 18-24mm. It’s an ideal lens for both photojournalism and general photographic needs.

    The superb functioning of the newly developed optical system ensures flawless synchronization with Nikon’s digital SLRs. The design — featuring ED (Extra-low Dispersion) glass elements for minimal chromatic aberration, and aspherical lenses including large-diameter PGM (Precision Glass Molding) elements to eliminate coma and other types of aberration even at the widest aperture — provide higher resolution and well-balanced aberration correction. Nano Crystal Coat, extra-low refractive index coating, virtually eliminates internal lens element reflections across a wide range of wavelengths, and is particularly effective in reducing ghosting and flare.

    Other important features include Nikon’s Super Integrated Coating that minimizes reflection in the wider wavelength range to ensure superior color balance and reproduction. Nikon’s exclusive SWM (Silent Wave Motor), incorporated in the lens body, ensures fast, quiet autofocus operation. M/A mode lets users switch quickly from automatic to manual focusing, even during AF servo operation, with virtually no time lag. The rounded diaphragm opening makes out-of-focus elements appear more natural. A fixed-type flower-shaped bayonet hood is supplied.

    The lens barrel is designed for secure holding, with zoom and focusing rings of the optimal diameter for smooth rotation, and rubber-coated to provide comfortable operation while ensuring ample ruggedness.

    The new ultra-wideangle, high-speed zoom lens is a significant addition to the NIKKOR lens lineup, offering serious photographers enhanced shooting flexibility for a broad range of applications.

    Note: Specifications, design, standard accessories, and release schedule may differ by country or area.
