Compatible with various Nikon F-mount cameras, the Sigma 500 mm f/4 DG OS HSM Sports Lens is an advanced, well-equipped tool that every professional photographer should have. It has a Super Multi-Layer coating on the lens elements to reduce lens flare and ghosting for producing contrast-rich, color-neutral imagery, even in low-light conditions. Use the built-in HSM (Hyper Sonic Motor), which features an optimized AF algorithm, to avail an instant, silent, and smooth autofocus performance. The Optical Stabilizer system is useful for compensating for about 4 shutter speed stops to capture sharper pictures. This lens also features a splash and dust-proof construction with a rubber sealing that helps in protecting the lens mount, along with oil- and water-repellent coating on the rear and front elements.
