20-60mm: Freedom to compose
From an expansive 20mm ultra-wide to a natural 60mm perspective, this lens delivers a wide range of expression in a versatile zoom. Capture everything from sweeping landscapes to everyday snapshots and portraits—without changing lenses.
With a maximum aperture of F2.8 at 20mm, you can shoot confidently in low light environments such as indoors and nightscapes, while keeping ISO low.
Bringing 20mm into your everyday
Weighing just 385g*1, this 3x zoom achieves an incredibly compact design—remarkable for an ultra-wide lens starting at F2.8. Its slim form fits easily into any bag, making it ideal for everything from daily snapshots and travel to hiking and video creation. Experience full-frame rendering performance with unprecedented portability.
*1. The figure is for L-Mount.
Consistent high optical performance across the entire zoom range
While prioritizing improved portability, no compromises have been made in image quality. The optical design—featuring 15 elements in 13 groups, including three aspherical lenses and three SLD glass elements—delivers consistent sharpness throughout the entire zoom range. From everyday scenes to breathtaking travel moments, it renders every detail with striking clarity.
Macro capabilities for versatile expression
Impressive close-up capability expands shooting versatility.
With a minimum focusing distance of 15.8 cm at 28mm and a maximum magnification ratio of 1:2.3 at 35mm, this lens delivers richly detailed close-up images approaching half-macro performance.
Even at the 60mm telephoto end, it maintains a high magnification of 1:2.9—ensuring a seamless shooting experience across the zoom range, allowing full focus on composition without concern for subject distance.
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.
Fast and quiet autofocusing with HLA system
A linear motor HLA (High-response Linear Actuator) is employed for the AF actuator, delivering high-speed autofocus with high-precision drive to capture decisive moments.
It also offers outstanding tracking performance for fast-moving subjects, even at high frame rates. Engineered for modern hybrid shooting, it ensures seamless performance across stills and video.
Minimal focus breathing
The lens is designed to minimize changes in the angle of view caused by focusing, enabling smooth, natural-looking focus pulls when recording video.
Dust- and splash-resistant structure*1 / water- and oil-repellent coating
In addition to a dust- and splash-resistant structure , the frontmost surface of the lens has a water- and oil-repellent coating applied, allowing photographers to shoot without concern even in harsh outdoor environments.
*1. 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.

MTF CHART
There are two types of MTF chart. One considers the diffraction quality of light, which is called "Diffraction MTF", and the other, "Geometrical MTF" does not.
The quality of light appears in the diffracted light, and becomes more distinct as the F value gets bigger, resulting in lower image quality. Also, diffracted light exists at every aperture, which is why Sigma has been releasing Diffraction MTF data from the beginning since it is very close to the actual image data.
The advantage of using "Geometric MTF" data is that it is easy to measure and calculate since it does not consider the diffraction quality of light, yet it tends to show higher values in the graph than actual images.
The readings at 10 lines per millimeter measure the lens's contrast ability ( red lines), repeating fine parallel lines spaced at 30 lines per millimeter measure the lens's sharpness ability (green lines), when the aperture is wide open.
Fine repeating line sets are created parallel to a diagonal line running from corner to corner of the frame, are called Sagittal lines (S) and sets of repeating lines vertical to these lines are drawn, called Moridional (M) line sets.
*The MTF chart gives the result at the wide-open aperture.

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.
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.
