Product Description

A Fast, Versatile APS-C Zoom Lens

Sigma unveils the 17-50mm f/1.8 DC Art Lens, a groundbreaking addition to its APS-C mirrorless lineup. Offering a constant f/1.8 aperture throughout the zoom range, this lens delivers prime-level image quality in a compact, wide-to-normal zoom—perfect for photographers and videographers looking to travel light without compromising performance.

Optics and Build Quality

Constructed with 17 elements in 11 groups, including four aspherical and four Special Low Dispersion elements, the lens is engineered to suppress flare, ghosting, and various optical aberrations. The result is exceptional clarity and contrast that matches or even surpasses other lenses in Sigma’s renowned Art series—such as the acclaimed 18-35mm f/1.8 DC HSM Art. Its 11-blade rounded aperture produces smooth, creamy bokeh while maintaining edge-to-edge sharpness at wide apertures.

The lens also boasts an 11″ minimum focusing distance across all focal lengths and achieves a maximum magnification ratio of 1:4.8, making it ideal for close-up shots and confined shooting environments.

Optimized for Video

Tailored for content creators, the lens features a constant f/1.8 aperture and a versatile zoom range that make it an excellent choice for solo shooters and run-and-gun filming. Internal zooming keeps the lens length consistent, ensuring better gimbal balance. Focus breathing is minimized for natural-looking transitions, and the high-speed linear actuator autofocus delivers fast, silent, and precise focusing. Manual focus benefits from a responsive click-and-lock mechanism for enhanced control.
