The Nikon AF-S DX VR Zoom-Nikkor 55-200mm f/4-5.6G IF-ED Lens is a versatile and ultra-compact telephoto zoom lens that offers a 3.6x zoom range, ideal for portraiture, sports or wildlife photography. Its equivalent focal length in 35mm terms, when used on a digital camera, is 82-300mm. It is the ideal companion to the DX 18-55mm f/3.5-5.6G ED standard zoom lens.The innovative Vibration Reduction (VR) system allows handheld telephoto zoom shooting even in poorly lit conditions. It minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 3 stops (8 times) faster. The Nikon Super Integrated Coating used in this lens minimizes ghosting and flare to provide even higher contrast and more vivid images, even in challenging light conditions.This G-type Nikkor lens is designed with no aperture rings, and offers easier, virtually mistake-free operation because the aperture does not need to be set to minimum.DX-Nikkor lenses are engineered and optimized for use on Nikon DX-format D-SLRs and are designed to cover the smaller image area of the DX sensor. When a DX lens is mounted on an FX-format Nikon D-SLR, the camera's DX-Crop Mode is automatically engaged, introducing a 1.5x magnification (cropping) factor.
