Specially built for professional photography, the Sigma 60–600mm F4.5–6.3 DG OS HSM Sports Lens ensures high-quality image reproduction while maintaining color accuracy. It is made for Sigma SA-mount cameras. Its optical design utilizes 25 elements that are arranged in 19 groups. The inclusion of three FLD and one SLD element minimizes various distortions throughout the zoom range. A water- and oil-repellent coating is given on the front element to prevent water and oil from taking hold on the surface. The Hyper Sonic Motor with AF override function suits fast-paced workflows where you need to switch the focus point between two subjects instantly. The intelligent optical image stabilization comes with an updated algorithm for reducing camera shakes by 4 stops, allowing you to obtain smooth and blur-free videos and images. There are special weather-proof seals on the lens barrel to keep dust and water outside. A tripod socket is included in the kit, which supports the lens when you have set up the camera on a tripod.
