Sigma 170-500mm f/5-6.3 APO Aspherical Lens for Nikon SLR Cameras

Detail for Black Friday Sale & Free Shipping! This great lens combines a 5-lens group zoom system with an aspherical lens element to deliver sharp high contrast images throughout the entire zoom range. Using Sigma s unique apochromatic lens design and three SLD glass elements, the aberrations usually found in ultra-telephoto lenses have been eliminated. And with Sigma s focusing system, the front lens group doesn t rotate, which makes using polarized filters a snap. A convenient built-in rotary tripod mount eliminates vibration during shutter release. One year international warranty.
