Encompassing all popular focal lengths from the 50mm "normal" to 500mm ultra- telephoto, the Sigma 50-500mm f4-f6.3 EX RF HSM hyperzoom lens gives you amazing versatility, plus a 10:1 zoom ratio, while its rear focus system ensures fast, convenient manual focus. The use of an apochromatic design plus four optical elements composed of special low dispersion (SLD) glass, a seven-group zoom system, and multicoated optics combine to give you high-quality images.
This lens, featuring Sigma's silent hypersonic motor (HSM) focusing system, allows you to shoot pictures of your subject without the normal noise of an automatic focus system. In addition to its quiet, responsive AF function, you can also use the full-time manual focus at any time. The zoom lock mechanism helps reduce the "zoom creep" distortion that can occur when your lens is tilted up or down.
Sigma used magnesium in the tripod mount to help reduce the weight of the lens, just over 65 ounces, yet still it still maintains the strength and rigidity necessary to support the lens's weight. This model is dedicated to Nikon AF SLR cameras.
