AF-S NIKKOR 24-70mm f/2.8G ED News Release
Nikon introduces new standard zoom NIKKOR lens with constant f/2.8 aperture
http://nikonimaging.com/global/news/...-s_24-70_i.jpgTokyo – Nikon Corporation is pleased to announce the introduction of a new standard AF-S Zoom-NIKKOR lens with constant f/2.8 aperture to further strengthen its zoom lens lineup. This new lens, together with the simultaneously introduced ultra-wideangle AF-S NIKKOR 14-24mm f/2.8G ED, and the existing AF-S VR Zoom-Nikkor 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 AF-S NIKKOR 24-70mm f/2.8G ED is a standard 2.9x zoom lens with a highly practical wideangle to medium-telephoto focal range, offering maximum versatility to accommodate everything from tight portraits to expansive scenes. With compact dimensions of Ø83 x 133 mm/Ø3.3 x 5.2 in. and a low weight of approx. 900 g/31.7 oz., it provides superb handling and outstanding portability.
The superior 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) element to eliminate coma and other types of aberration even at the widest aperture— delivers brilliant overall optical performance. 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 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.
This new zoom lens is the latest addition to an already formidable lineup, offering photographers enhanced shooting flexibility.
Note:
Specifications, design, standard accessories, and release schedule may differ by country or area.
