The All-New Sigma 17-40mm F1.8 DC | Art

We are proud to announce the new Sigma 17-40mm F1.8 DC | Art. This lightweight, compact addition offers portability and a large aperture for APS-C photographers and videographers.

The 17-40mm F1.8 DC | Art is the natural successor to the Sigma 18-35mm F1.8 DC HSM | Art, providing high shooting flexibility for both still images and video. Designed with video shooting in mind, you’re sure to see Sigma’s first APS-C Art lens designed for mirrorless cameras on the wishlist of all creatives.

Equipped with an inner zoom mechanism, the 17-40mm F1.8 DC Art ensures smooth focusing and high optical performance. The F1.8 large-aperture standard zoom has a compact and lightweight design that makes it the perfect lens for videographers and brings unmatched specifications to the APS-C format, showcasing Sigma’s unique expertise and technological advancement.

Features include:

• A constant maximum aperture of F1.8 across the entire zoom range
• SLD glass to suppress chromatic aberration and coma flare
• Lightweight and compact size
• Inner zoom mechanism
• High-response Linear Actuator technology to suppress focus breathing
• Aperture ring with various functional options
• Water- and Oil-Repellent coating
• Dust and splash resistant

Design and Performance

The lens features a total of 17 elements in 11 groups, with four aspherical and four Special Low Dispersion elements to minimize flare and ghosting and suppress various aberrations. This results in an optical performance that meets or exceeds that of other Sigma Art lenses, including the 18-35mm f/1.8 DC HSM Art lens. Along with its 11-blade, rounded diaphragm, the design promotes sharpness and a large, smooth bokeh when used wide open. 

In addition to the f/1.8 maximum aperture, the lens also maintains an 11″ minimum focusing distance across the entire zoom range. It achieves a maximum magnification ratio of 1:4.8 at its longest focal length, increasing depth of field and versatility in tight spaces.

Video Production

Designed with video creation in mind, the lens’ bright f/1.8 aperture and wide-to-normal zoom range make it a versatile tool ideal for single-shooter, run-and-gun setups. An internal zoom design maintains the overall length during use, making it easy to balance on gimbals. The design also suppresses focus breathing for smooth movement across the focal range. Sigma’s high-speed, high-response linear actuator autofocus remains both quiet and accurate, while manual focusing is improved with click-and-lock mechanisms.
