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

The AF-S NIKKOR 14-24mm f/2.8G ED Lens from Nikon is an ultra-wide-angle zoom lens with a constant f/2.8 maximum aperture that delivers edge-to-edge sharpness, and high contrast, and is a staple in the kits of advanced Nikon shooters. It features Nano Crystal and Super Integrated Coating to improve light transmission and reduce the effects of ghosting and flare. Two ED (Extra-low Dispersion) elements and three aspherical lenses control chromatic and spherical aberrations and combine to enhance sharpness and contrast. Designed for FX-format DSLRs it is also compatible with DX-format cameras on which it offers the 35mm focal length equivalence of 21-36mm. The Silent Wave Motor (SWM) and internal focus system provide swift autofocus with superior accuracy and ultra-quiet operation. This G-type lens does not feature an aperture ring on the lens body, resulting in a lighter and more compact lens. Aperture changes are designed to be done via the camera's command dial. A magnesium alloy build with dust and moisture-resistant sealing allows this lens to be used in inclement conditions and a built-in lens hood offers a degree of protection to the otherwise exposed front lens element. , NK1424G Nikon AF-S NIKKOR 14-24mm f/2.8G ED Lens CL-M3 Semi-soft Case Built-in Flower Type Hood Features: Fast, ultra wide-angle AF-S zoom lens optimized for edge-to-edge sharpness on both the Nikon FX (23.9 x 36mm) and DX format image sensors Enhanced optical formulas, engineered to produce exceptional sharpness, contrast and color, rendering outstanding image integrity Two ED (Extra-low Dispersion) elements and PGM aspherical lenses control chromatic aberrations, while enhancing sharpness and contrast, even at the widest aperture settings Exclusive Nano Crystal Coat further reduces ghosting and flare for even greater image clarity Nikon's Silent Wave Motor (SWM) enables ultra high-speed autofocusing with exceptional accuracy and powerful, super-quiet operation Internal Focus (IF) provides fast and quiet autofocusing without changing the length of the lens, retaining subject-working distance through the focus range Focus as close as 10.8 inches at the 24mm setting Rugged construction and professional-grade dust and moisture resistance M/A Focus Mode switch enables quick response to changing situations between Auto and Manual focus operation Specifications: Focal length: 14-24mm Maximum aperture: f/2.8 Minimum aperture: f/22 Lens construction: 14 elements in 11 groups Minimum focus distance: 0.9 feet (telephoto) Maximum reproduction ratio: 1/6.7 No. of diaphragm blades: 9 (rounded) Focusing: Internal Focusing (IF) system; autofocus with a built-in SWM and manual focus Picture Angle: 114 - 84 degrees (90 - 61 degrees with DX-format) Hood: Fixed-type flower shaped bayonet hood supplied Dimensions: approximately 3.9 in. x 5.2 in.
