12-24 mm f/4G ED-IF AF-S DX Zoom-Nikkor Lens

The DX Nikkor 12-24mm f/4G lens - designed to operate exclusively with Nikon D-Series digital SLR cameras and their DX Format sensors - was developed as the first lens in a new F-Mount autofocus DX-Nikkor interchangeable lens category. The DX 12-24mm f/4G lens is designed to address the need for wider angle-of-view, high- performance optics for digital SLR photography and is optimized for DX Format sensors used in Nikon digital SLR cameras. Designed for Nikon D-Series digital SLR Design enables a combination of wider angle-of-view with optical characteristics that are optimized for Nikon digital SLR camera sensors 2x Zoom ratio and variable angle-of-view from 99 degrees at 12mm to 61 degrees at 24mm. Comparable to that of an 18-36mm lens on 35mm size sensor format Nikon design that produces a smaller image circle (the size of the image that is projected by the lens on to the sensor) enabling smaller lens diameter, and optimal image quality from center-to-edge-to-corner on the image Exclusive Silent Wave Motor enables ultra-high-speed autofocusing with exceptional accuracy and powerful super-quiet operation 2 Extra-Low Dispersion (ED) glass elements for minimized chromatic aberration 3 Aspherical lens element for low distortion Internal Focusing (IF) design for smoother focusing and great body balance M/A mode enables instant switching from autofocus to manual with virtually no time lag even during AF servo operation Nikon D-type design provides precise distance information for flash and ambient light exposure processes Rounded diaphragm to make out-of-focus elements appear more natural DX Nikkor is designed exclusively for use with Nikon Digital SLR models 11.8 close focusing distance throughout zoom range Atypical of lenses with similar focal lengths, the DX 12-24mm f/4G lens is very compact and lightweight, offering a 2X Zoom ratio with an unprecedented angle-of-view from 61o at 24mm to 99 o at 12mm. This range of angle-of-view is comparable to that of an 18-36mm lens on the 35mm format. The lens also incorporates many of Nikon's advanced technologies including Nikon Super Integrated Coating (SI-C), Silent Wave Motor Technology (SWM), Extra Low Dispersion Optical Glass (ED) and a G-Type design. Nikon digital SLR photographers have enthusiastically enjoyed the inherent benefits of the DX Format sensor size used in Nikon D-Series SLR cameras. Each original 35mm lens achieves a 1.5x factor for angle-of-view when used with Nikon D-Series digital SLR cameras, enabling smaller and lighter lenses to emulate the angle of view of normally larger, heavier and more costly optics. With the introduction of the new DX 12-24mm f/4G lens, photographers can now enjoy the benefits of Nikon's DX Format Sensor size on the wide-angle end of the lens spectrum. Revolutionary in terms of its compact size, weight, zoom ratio, optical performance and angle-of-view out to an exceptional 99-degrees. Nikon designers determined that by reducing the diameter
