Sigma 170-500mm f/5-6.3 APO Aspherical RF Telephoto Zoom Lens for Sigma AF

The Sigma 170-500mm f/5-6.3 APO Aspherical RF is a powerful superzoom telephoto lens designed for Sigma AF mount cameras, covering a versatile focal range from 170mm to 500mm — making it an outstanding choice for wildlife photography, bird photography, sports, motorsport, and any situation where you need to reach distant subjects without sacrificing image quality. The APO (apochromatic) optical design uses special low-dispersion glass elements to minimise chromatic aberration and colour fringing, delivering sharp, high-contrast images across the entire zoom range.

The lens features Sigma’s RF (rear focus) autofocus system for fast, quiet focusing performance, an aspherical element to control distortion and aberrations, and a built-in tripod collar for stable shooting at longer focal lengths. The minimum focus distance of 1.8 metres allows for surprisingly close focusing at 170mm, adding versatility for nature and detail shots. The robust, professional-grade barrel construction is designed to withstand the demands of outdoor and field photography.
