The Sigma APO 50-500mm f4-6.3 EX DG HSM lens is more than a mouthful to quote in full,  but one thing remains, it is a powerful 10x zoom lens for SLR & D-SLR cameras.

 This lens is a great choice for photographers who shoot everything from fashion to wildlife, but don't want to carry a truckload of different lenses.

 The lens has Sigma's HSM AF motors for rapid, near silent AF performance* as well as a rear focus system that eliminates the rotating front element that allows the use of polarising filters & petal type lens hoods to reduce flaring.

* HSM only available on Canon EF & Nikon D mounts
