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. *1 The figures are for L-Mount.
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.
Lens Construction
MTF CHART
The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1). The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is. *The MTF chart depicts the result at the wide-open aperture. *For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.) *The spatial frequency indicates the variation on the image plane before distortion correction is performed.

HLA (High-response Linear Actuator)
HLA is Sigma's proprietary linear motor. It drives the focus lens directly without going through gears or other mechanical parts, resulting in quiet, high-precision autofocusing.
Water and oil repellent coating
Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.
Focus Mode Switch
Using this swich, it is possible to switch the focus mode between AF and MF.
Zoom lock switch (Wide end)
The zoom lock switch fixes the zoom ring at the widest end, preventing it from rotating and causing the lens barrel to extendunder its own weight during transportation.
Dust and Splash Resistant Structure
This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection. *Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.
Mount Conversion Service available
upport for switching between linear and non-linear focus ring settings (for L-Mount only)* * Only cameras that are compatible with the system are allowed to use the system.
