Sigma's upgrade for its popular 50-500mm ultra-telephoto zoom the 50-500mm F4.5-6.3 DG OS HSM now incorporates Optical Stabilisation - a hugely welcome addition to such a long lens. Sigma claims the OS offers up to four stops benefit, and works with Sony and Pentax SLRs as well as Canon, Sigma and Nikon models, with the stabilized viewfinder image aiding in focusing and composition. The all-new optical design uses 22 elements in 16 groups, including four SLD glass elements, but the filter size has grown to a whopping 95mm.
This 50-500mm f/4.5-6.3 APO DG OS HSM Lens from Sigma is a zoom lens for digital SLR cameras with a Nikon lens mount. The lens has a standard to ultra telephoto zoom range that is ideal for nature, wildlife, or sports photography. The range translates into an equivalent 75-750mm when used with digital SLR cameras with an APS size chip. The lens is also compatible with full frame cameras. You can even increase you telephoto range by using the Sigma APO teleconverters.
