Sigma 17-40mm f/1.8 DC Art Lens: Bright, Wide-to-Normal APS-C Zoom
Sigma introduces a game-changer for APS-C mirrorless cameras: the new 17-40mm f/1.8 DC Art Lens. This exceptional zoom boasts a constant f/1.8 aperture across the entire zoom range, offering prime-like optical performance and a video-friendly design. Its versatile wide-to-normal focal length means you can carry a lighter kit bag without compromising on image quality.

Uncompromising Design and Performance
The lens is meticulously crafted with 17 elements in 11 groups, including four aspherical and four Special Low Dispersion elements. This sophisticated optical construction works to minimize flare, ghosting, and various aberrations, delivering an optical performance that meets or even exceeds other acclaimed Sigma Art lenses, such as the 18-35mm f/1.8 DC HSM Art lens. Coupled with an 11-blade, rounded diaphragm, this design promotes exceptional sharpness and large, smooth bokeh when used wide open.

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

Optimized for Video Production
Designed with video creators in mind, the 17-40mm f/1.8’s bright aperture and wide-to-normal zoom range make it an incredibly versatile tool for single-shooter, run-and-gun setups. An internal zoom design maintains the overall length during use, which is crucial for easy balancing on gimbals. This design also effectively suppresses focus breathing for smooth transitions across the focal range. Sigma’s high-speed, high-response linear actuator autofocus remains both quiet and accurate, while manual focusing is improved with convenient click-and-lock mechanisms.

Additional Features:
Two customizable AFL buttons for enhanced control.
Dedicated focus mode switch.
Water- and oil-repellent coating on the front element for easy cleaning.
Dust- and splash-resistant design for durability in various conditions.
Durable brass bayonet mount ensures a secure connection.
This lens is set to become a favorite for APS-C mirrorless shooters who demand both versatility and uncompromising optical quality.
