High-power zoom starting at 20mm for versatile shootingWorld's first 10x zoom lens starting at an ultra-wide angle of 20mmThe Sigma 20-200mm F3.5-6.3 Dg | Contemporary is a 10x zoom lens that achieves a wide angle of 20mm, which is much wider than typical high-power zoom lenses. You can shoot expansive landscapes and large buildings in their entirety, as well as impressive close-ups, without changing lenses. Even when traveling with limited luggage, this single lens allows for a wide variety of shots.Maximum magnification ratio of 1:2The Sigma 20-200mm F3.5-6.3 Dg | Contemporary achieves a maximum magnification ratio of 1:2 at a focal length of 28mm to 85mm. At 28mm, you can capture a broad background to emphasize depth, while at 85mm, you can arrange the background and blur it extensively for a clean look. This lens also offers versatile expression capabilities for close-up photography. It also achieves a magnification ratio of 1:3.3 at the telephoto end of 200mm, enabling high magnification shooting across a wide range of focal lengths.Optical and mechanical design that combines compact size and high performanceThe Sigma 20-200mm F3.5-6.3 Dg | Contemporary is a full-frame compatible high-power zoom lens with an unprecedented ultra-wide 20mm start, yet it is shorter and lighter than the Sigma 16-300mm F3.5-6.7 Dc Os | Contemporary, a high-power zoom lens for Aps-c cameras.By incorporating high-refractive-index glass, the lens reduces the amount of movement required during zooming, achieving a compact and lightweight design. The optical design, which properly positions four aspherical lenses, one Fld glass element, and three Sld glass elements, combined with an internal mechanism that precisely maintains each zoom group, enables high performance across the entire zoom range despite the high zoom ratio.Reliability and operabilityHigh-speed Af with HlaThe HLA (High-response Linear Actuator) with high thrust drives a lightweight focus lens group, enabling extremely fast autofocus. You can capture every moment without missing a shot.Dust- and splash-resistant structureA dust and splash-resistant structure with sealing around the mount joint and other parts prevents dust and water from entering the lens barrel during outdoor shooting. In addition, a water and oil-repellent coating on the front element of the lens makes maintenance easy when water droplets or dust adhere to the lens. Even outdoors, you can shoot with confidence.Note: The product is designed to be dust and splash-resistant but is not waterproof. When using the lens near water, etc., take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction and render the lens unrepairable.Zoom lock switchThe lens is equipped with a zoom lock switch to prevent accidental extension due to its own weight while being carried. The lock is released by operating the zoom ring, allowing you to respond immediately to photo opportunities.Focus breathingThe Sigma 20-200mm F3.5-6.3 Dg | Contemporary has minimal breathing at both wide and telephoto end..
