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.
