Nikon AF-S NIKKOR 24-70mm f/2.8G ED Telephoto Zoom Lens 2164

With a fast fixed aperture of f/2.8 across a 24–70mm zoom range, the Nikon AF-S NIKKOR 24-70mm f/2.8G ED lens provides both fine resolution and natural representation. A Nano Crystal Coat helps effectively reduce ghost and flare effects under harsh lighting for greater image clarity. Its Internal Focus (IF) provides fast and quiet auto focusing without changing the length of the lens, so you can retain subject to working distance through the entire focus range.The AF-S NIKKOR 24-70mm f/2.8G ED delivers fast, wide-angle to medium telephoto zoom capabilty and is optimized for edge-to-edge sharpness on both Nikon FX and DX format D-SLRs. Its fast, fixed f/2.8 aperture enables exceptional low-light performance and consistent exposure across the entire zoom range. Enhanced optical formulas produce exceptional sharpness, contrast and color, rendering outstanding image and video integrity.The AF-S NIKKOR 24–70mm f/2.8G ED lens's rugged construction includes professional-grade dust and moisture resistance. Three Extra-low Dispersion (ED) glass elements and Precision Glass Mold (PGM) Aspherical lens elements control chromatic aberrations while enhancing sharpness and contrast, even at the widest aperture settings; and Nikon's Silent Wave Motor (SWM) enables ultra high-speed auto focusing with pinpoint accuracy and super-quiet operation.AF-S NIKKOR lenses featureNikon'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.ASstands 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.Nikon AF-S NIKKOR 24-70mm f/2.8G ED Telephot Zoom Lens Specifications:Mount Type: Nikon F-BayonetFocal Length Range: 24-70mmZoom Ratio: 2.9xMaximum Aperture: f/2.8Minimum Aperture: f/22Format: FX/35mmMaximum
