The go-to lens of demanding professionals and serious enthusiasts, the 70-200mm f/2.8 is one of the most useful and sought after high-performance lenses for sports, wildlife, portrait, travel and news photographers. Nikon has further refined the lens, with an enhanced optical formula featuring seven extra low dispersion (ED) glass elements. These elements provide the ultimate in rendering characteristics to capture vibrant, high resolution images with optimal contrast. Image quality is further enhanced by Nikon's Nano Crystal Coat, which reduces instances of lens flare and ghosting, elevating optical performance, even in tricky conditions such as those found in professional sports settings and stage events. Designed to deliver the pinnacle of image quality in a wide variety of conditions, the new 70-200mm VR II lens also includes a Silent Wave Motor (SWM) for fast, quiet autofocusing. The SWM takes full advantage of 3D tracking autofocus (AF) systems, such as those found on the FX-format D3X, D3 and D700 D-SLR cameras. Three focus modes are available - M, A/M and M/A - for automatically focusing, manually focusing or fine tuning AF performance to best suit the photographers' needs. Nine rounded diaphragm blades contribute to a more attractive bokeh, allowing photographers create soft and more naturally separated backgrounds that better highlight the subject.
