The Nikon AF-S Nikkor 24-70mm f/2.8G ED Autofocus Lensis a fast aperture standard zoom lens designed for photojournalism and general photography. Optimized for edge-to-edge sharpness on both the Nikon FX (full-frame) and DX-format image sensors, this lens also includes two ED (Extra-low Dispersion) elements and PGM aspherical lenses that help control chromatic aberrations while enhancing sharpness and contrast, even at the widest aperture settings.
The Silent Wave Motor (SWM) feature provides 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.
Note: AF-S feature is not supported by certain older camera models. "G" type lenses are not fully compatible with the F4, N90-series, N70, N8008-series and N6006 (or older model) cameras, only programmed auto or shutter-priority auto exposure mode can be used.
