This 50-500mm f/4.5-6.3 APO DG OS HSM Lens for Nikon 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. The OS (Optical Stabilizer) system minimizes image blur caused by camera shake, and offers the equivalent of shooting at a shutter speed 3-4 stops faster.
