The Sigma 20-200mm F3.5-6.3 DG Contemporary is a compact and lightweight zoom lens for Sony full-frame mirrorless cameras. This versatile zoom lens covers everything from ultra-wide 20mm to telephoto 200mm, allowing photographers to capture subjects ranging from sweeping landscapes to fast-paced sports without being constrained by distance. Its flexibility makes it ideal for a wide variety of scenes, including close-ups with a maximum magnification ratio of 1:2. With its broad expressive capabilities, the lens truly shines in travel photography and everyday snapshots. Compact and lightweight design This lens weighs only 550g and measures just 115.5mm in length. The zoom ring diameter is a very slim 70.4mm, making it highly portable. Without worrying about size or weight, the lens provides extensive creative flexibility in any situation, from everyday snapshots to travel photography. Optical and mechanical design Incorporating high-refractive-index glass materials reduces lens movement during zooming. This enables a simple internal structure and slim lens body. The optical design, which properly positions four double-sided aspherical lenses, one FLD glass, and three SLD glass elements, combined with an internal mechanism that maintains high precision in each zoom group, also delivers high performance across the entire zoom range. HLA-driven high-speed AF To help photographers capture even the most fleeting moments, the lens uses an HLA (High-response Linear Actuator) to achieve high-speed autofocus functionality with excellent drive accuracy. Dust and splash-resistant structure plus water and oil-repellent coating In addition to a dust and splash-resistant structure, the front element of the lens features a water- and oil-repellent coating, allowing photographers to shoot without concerns even in harsh outdoor environments. Equipped with a zoom lock switch The lens features a zoom lock switch that can be fixed at the wide end to prevent the lens from extending unintentionally under its own weight. The lock can be released not only by the switch but also via zoom operation, allowing for flexible handling of even impromptu shooting. Designed to minimize flare and ghosting Flare and ghosting, which reduce image quality, are addressed under all conditions of incident light, based on the most advanced simulation technology. High backlight resistance enables clear and sharp images under any lighting conditions.
