Sigma 20-200mm f/3.5-5.6 DG Contemporary Lens

Capture everything from sweeping landscapes to tight sports action, all without changing a lens, with the 20-200mm f/3.5-6.3 DG Contemporary Lens from Sigma. The ultimate all-in-one zoom, this lens remains portable without sacrificing sharpness or autofocus performance. With a maximum magnification ratio of 1:2 for close-up shots, a maximum aperture of 6.3 at 200mm, and a durable construction for any situation, this lens may never leave your camera once attached. Versatile Construction Weighing only 1.2 lb and measuring 4.5" when not extended, the lens is extremely portable while boasting a massive zoom range from ultra-wide 20mm to telephoto 200mm. The lens features a focus mode switch as well as a zoom lock to prevent it from extending under its own weight. The zoom lock can also be released via zoom operation, ensuring the lock won't make you miss a shot. A water- and oil-repellent coating on the front lens element makes it possible to shoot in harsh outdoor environments, while the dust- and splash-resistant construction keeps the internal elements protected. Innovative Optical Design Sigma combines four aspherical elements, three Special Low Dispersion (SLD) elements, and one F Low Dispersion (FLD) element to ensure clarity throughout the zoom and aperture range. A total of 18 elements in 14 groups, as well as a 9-blade rounded diaphragm, maintain high optical precision across the zoom range while keeping the lens compact and light. Advanced simulation technology has been used to optimize backlight resistance, minimizing potential lens flare and ghosting. High-Speed Autofocus Rely on the lens to capture the briefest moments thanks to Sigma's HLA (High-response Linear Actuator) focusing system for fast and quiet autofocusing throughout the entire focusing range.
