Nikon 80-200mm f/2.8 AF-S lens

Nikon 80-200mm f/2.8 AF-S lens























Nikon has brought the advantages of its Silent Wave Motor and Autofocus (AF) technologies to the photojournalism, action and low-light categories with AF-S Zoom-Nikkor 80-200mm f/2.8D IF-ED lens. The new lens incorporates AF-S Nikkor lens technology, which provides faster and more accurate autofocus operation, along with an all-new optical design to make them smaller and lighter for more effective field use.
Autofocus performance is formidable, allowing the user to shoot up to eight perfectly focused frames per second, with Focus Tracking and Lock-On. The lens is also perfectly balanced, with Internal Focusing (IF) for ultra-fast autofocus performance, compact design, lightweight construction, critical balance and closer focusing ability. In addition, Nikon's exclusive Silent Wave Motor (SWM) technology enables swifter autofocusing with exceptional accuracy and powerful, whisper-quiet operation.
Each AF-S Nikkor lens' Silent Wave Motor interfaces directly with the lenses' focusing elements. Because there is no gear-train, there is none of the power loss or noise associated with conventional gear-type lens driving systems.Virtually silent, Nikon's AF lenses provide significant advantages. AF-S Zoom-Nikkor 80-200mm f/2.8D IF-ED lens boasts a newly-designed optical system, demonstrating Nikon's unsurpassed status as the world's preeminent designer of high-performance optics. With exclusive Extra-Low Dispersion (ED) optical glass, and for the wide-angle zoom a new molded-glass aspherical lens design, the lens offers minimized distortion and chromatic/spherical aberration, while delivering superior resolution, color brilliance, brightness and contrast.
A nine-blade, rounded diaphragm makes out-of-focus elements in the picture appear more natural. The advanced M/A mode featured in all AF-S Nikkor lenses allows the photographer to switch instantly from autofocus to manual performance, even during AF servo operation, with virtually no time lag. As with all AF and AF-S Nikkor lenses, there is no power consumption. Comfort and usability are ensured with a wide variety of features for streamlined performance. A rotating zoom ring offers precise zoom control, and the filter attachment does not rotate during focusing and zooming. AF-S Zoom-Nikkor 80-200mm f/2.8D IF-ED is provided with the detachable tripod-mounting collar. In addition this lens is built to be dust- and moisture-resistant.
