Sigma 17-40mm f/1.8 DC Art Lens for Sony E

The Sigma 17-40mm f/1.8 DC Art is a professional APS-C zoom that combines an exceptionally bright constant f/1.8 aperture with image quality designed to rival prime lenses. Its approximately 26–60mm full-frame-equivalent range covers wide-angle storytelling, everyday photography, environmental portraits and natural-perspective video.

Fast HLA autofocus, internal zooming and extensive manual controls make it equally capable for high-end still photography and professional Sony video production.

📷 Versatile 26–60mm-Equivalent Range

On a Sony APS-C camera, the 17-40mm range provides an angle of view comparable to approximately 26–60mm on full frame.

This range moves smoothly from wide environmental compositions to natural-perspective portraits and detail shots:

• 17mm for landscapes, interiors and establishing shots

• 24mm for documentary and environmental portraits

• 30mm for everyday storytelling

• 40mm for tighter portraits, products and details

🌙 Constant f/1.8 Aperture

The constant f/1.8 maximum aperture is significantly brighter than the f/2.8 aperture found on most professional zooms.

It allows photographers and filmmakers to:

• Use faster shutter speeds in low light

• Maintain lower ISO settings

• Create stronger background separation

• Keep exposure consistent while zooming

• Work effectively with available light

• Achieve a cinematic shallow depth of field

🔍 Prime-Like Art-Series Optics

The sophisticated optical design uses 17 elements in 11 groups, including four SLD glass elements and four aspherical elements.

These specialized components suppress chromatic aberration, distortion and other optical imperfections while maintaining excellent detail throughout the zoom range. The lens is designed to deliver professional results even at its maximum f/1.8 aperture.

⚡ HLA High-Speed Autofocus

Sigma’s High-response Linear Actuator provides fast, accurate and quiet autofocus.

The HLA system responds quickly when photographing moving subjects while providing smooth transitions during video. It works with compatible Sony face-, eye- and subject-detection autofocus features.

🔄 Internal Zoom Construction

The lens remains approximately the same length throughout its zoom range. This internal zoom design helps maintain consistent balance and prevents the barrel from extending toward the subject.

Internal zooming is particularly valuable when working with:

• Motorized gimbals

• Matte boxes

• Follow-focus systems

• Camera cages

• Rain covers

• Confined shooting positions

🎥 Built for Professional Video

The 17-40mm f/1.8 includes several features intended specifically for filmmaking:

• Minimal focus breathing

• Quiet HLA autofocus

• Internal zooming

• Clickless aperture operation

• Stable exposure throughout the zoom

• Consistent center of gravity

• Smooth manual controls

These features make it a strong match for the Sony FX30 and other APS-C or Super 35 video cameras.

🎛️ Professional Aperture Controls

The physical aperture ring provides direct exposure control. A de-click switch allows smooth, silent aperture adjustment during video, while the aperture-ring lock helps prevent accidental setting changes.

The lens also includes an AFL button that can be assigned to compatible camera functions.

🌸 Close-Focusing Performance

A minimum focusing distance of approximately 28cm applies throughout the zoom range.

At 40mm, the lens reaches a maximum reproduction ratio of 1:4.8, making it useful for products, food, wedding details and tightly framed environmental subjects.

✨ Smooth Background Rendering

An 11-blade rounded diaphragm helps produce smooth out-of-focus highlights and natural background transitions.

Combined with the f/1.8 aperture, it allows the lens to create subject isolation normally associated with fast prime lenses.

🪶 Lighter Than Its DSLR Predecessor

The 17-40mm builds upon the concept introduced by Sigma’s celebrated 18-35mm f/1.8 DSLR lens while providing:

• A wider 17mm starting position

• Additional reach to 40mm

• More than 30% lower weight

• Native mirrorless construction

• Faster HLA autofocus

• Internal zooming

• Modern video controls

The Sony E-mount version weighs approximately 525g, making it considerably easier to use handheld or on a gimbal.

🌦️ Professional Art-Series Construction

Dust- and splash-resistant construction provides additional confidence during location work. A water- and oil-repellent coating on the front element makes fingerprints, moisture and dirt easier to remove.

Sigma’s Thermally Stable Composite and precision metal components provide strength while controlling overall weight.
