Sigma 17-40mm f/1.8 DC DN Art Lens: Prime-Like Performance in an APS-C Zoom

Sigma introduces a groundbreaking new zoom lens for APS-C mirrorless cameras: the 17-40mm f/1.8 DC DN Art Lens. Boasting a constant f/1.8 aperture throughout its entire zoom range, this lens delivers prime-like optical performance in a versatile wide-to-normal focal range. This means you can carry a lighter kit bag without ever compromising on image quality.

Exceptional Optical Design
The 17-40mm f/1.8 DC DN Art is engineered for optical excellence:

Its sophisticated design features 17 elements in 11 groups, including four aspherical and four Special Low Dispersion (SLD) elements. These work in concert to minimize flare, ghosting, and various aberrations, ensuring stunning sharpness and clarity.

This lens achieves an optical performance that meets or exceeds that of other acclaimed Sigma Art lenses, including the popular 18-35mm f/1.8 DC HSM Art.

Coupled with an 11-blade, rounded diaphragm, the design promotes incredible sharpness and a large, smooth bokeh when used wide open, making your subjects truly pop.

The lens maintains an impressive 11-inch minimum focusing distance across the entire zoom range, achieving a maximum magnification ratio of 1:4.8 at its longest focal length, increasing versatility in tight spaces.

Optimized for Video Production
Designed with video creation in mind, the 17-40mm f/1.8’s bright f/1.8 aperture and wide-to-normal zoom range make it an incredibly versatile tool, ideal for single-shooter, run-and-gun setups.

An internal zoom design maintains the overall length of the lens during use, making it easy to balance on gimbals and ensuring consistent performance.

This design also suppresses focus breathing for smooth, cinematic focus pulls across the focal range.

Sigma’s high-speed, high-response linear actuator autofocus remains both quiet and accurate, ensuring your subjects stay sharp without distracting noise.

Manual focusing is improved with click-and-lock mechanisms, providing tactile feedback and precise control for videographers.

Robust Build and Intuitive Features
The Sigma 17-40mm f/1.8 DC DN Art is built for demanding environments and intuitive handling:

Two customizable AFL buttons allow for quick access to assigned functions.

A dedicated focus mode switch provides seamless transitions between autofocus and manual focus.

A water- and oil-repellent coating on the front element helps keep the lens clean and makes maintenance easier.

A dust- and splash-resistant design ensures reliable performance in challenging conditions.

A durable brass bayonet mount provides a secure and precise connection to your camera body.
