Description:
Sigma combined a five-lens group zoom system with an aspherical lens element when they designed the 170-500mm f5-f6.3 APO aspherical lens. This combination gives your images sharp high-contrast images throughout the entire zoom range. Its unique apochromatic lens design and three SLD glass elements help eliminate the vibrations usually found in ultra-telephoto lenses. Since the front lens group doesn't rotate, polarized filters are extremely easy to use. This lens also has a built-in rotary tripod mount to help keep the lens steady, reducing vibration during shutter release and keeping your images sharp and clear. This model is dedicated to Canon AF SLR cameras.
