Sigma 20-200mm f/3.5-6.3 DG Contemporary Lens
All-in-One Superzoom – Ultra-Wide 20mm to Telephoto 200mm Range, HLA AF Motor, 1:2 Macro Ratio & Compact Weather-Sealed Housing

The Sigma 20-200mm f/3.5-6.3 DG Contemporary is an all-in-one superzoom lens engineered for full-frame mirrorless camera systems. Spanning an expansive focal range from an ultra-wide 20mm to a telephoto 200mm, this versatile optic empowers creators to capture everything from sweeping landscapes and architecture to tight sports action and portraits without changing lenses. Despite its massive zoom range, the lens maintains an ultra-portable form factor, measuring 4.5 inches in length and weighing just 1.2 lb.

Its complex optical design incorporates 18 elements in 14 groups, including four aspherical elements, three Special Low Dispersion (SLD) elements, and one F Low Dispersion (FLD) element to maintain edge-to-edge sharpness and suppress chromatic aberrations throughout the zoom spectrum. Powered by Sigma’s High-Response Linear Actuator (HLA) motor system, the lens delivers fast, quiet, and precise autofocus performance. For close-up photography, it offers a maximum magnification ratio of 1:2. The weather-sealed chassis features a water- and oil-repellent front element coating, a focus mode switch, a rounded 9-blade diaphragm, and a smart zoom lock switch that can be disengaged instantly by turning the zoom ring.
