Sigma 20–200mm F3.5–6.3 DG Contemporary Lens

• Zoom versatility meets expressive ultra-wide 20mm ― in one lens.

The lens covers the ultra-wide angle of 20mm, which has been difficult to achieve with conventional high-power zoom lenses. Handling everything from majestic landscapes to sports, the lens perfectly captures both scenes unique to ultra-wide angles and applications that take advantage of its telephoto range. With a comprehensive zoom range of 20mm to 200mm, this ultimate all-in-one zoom lens delivers stunning details across a wide variety of shooting situations.

• Maximum magnification ratio of 1:2 at the focal lengths of 28-85mm

The lens achieves a maximum magnification ratio of 1:2 at the focal lengths from 28mm to 85mm, enabling photographers to enjoy a broad range of half-macro photography with different angles of view, from wide macro shots that boldly incorporate the background by moving closer to the subject, to medium telephoto macro shots that highlight the subject at a natural distance.

• Thoroughly compact and lightweight design

This lens is the world's first to achieve a vast zoom range from ultra-wide 20mm to telephoto 200mm, while weighing only 550g and measuring just 115.5mm in length^*1. 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 realizing both compact size and high performance

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^*1 and 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.

*1 The structure is designed to be dust- and splash- resistant, but not waterproof. Be careful not to bring the lens in contact with a large amount of water. Water inside the lens may cause major damage and even render the lens unrepairable.

• Equipped with a zoom lock switch at the wide end

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.
