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.

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.Separate focusing elements work together to maintain focus throughout the entire zoom range.
