Sigma 17-40mm F1.8 DC | Art

Overview
A standard zoom lens with a large F1.8 aperture and exceptional image quality comparable to prime lenses across the entire zoom range.
Designed for APS-C mirrorless cameras, this lens pushes the boundaries of still and video photography expression.
The Sigma 17-40mm F1.8 DC | Art builds on the innovations of the Sigma 18-35mm F1.8 DC HSM | Art, which was the world’s first zoom lens with an F1.8 aperture.

Major Improvements

• More than 30% lighter
• Improved optical and physical design for better portability

Key Features

Prime-like Optical Power

• Ideal for low-light conditions and soft background blur

Outstanding Optical Performance

Flexible Framing
Zoom range: 17–40mm (equivalent to 25.5–60mm in full-frame). Covers wide-angle to portrait scenarios without changing lenses.
