The Sigma 17-40mm F1.8 DC Art (Fuji X) is a groundbreaking APS-C zoom lens offering a constant f/1.8 aperture, making it one of the fastest zooms available for mirrorless cameras. It’s designed for both stills and video, delivering prime-like sharpness, minimal focus breathing, and excellent low-light performance.
The Sigma 17-40mm F1.8 DC Art (A025) is a wide-to-standard zoom lens built for Fujifilm X-mount APS-C mirrorless cameras. It expands on Sigma’s legacy of fast zooms, following the acclaimed 18-35mm f/1.8, but with a broader focal range and lighter build.
Constant f/1.8 aperture: Bright performance across the zoom range, ideal for low-light and shallow depth of field.
Wide-to-standard zoom: Covers 17–40mm (≈25.5–60mm full-frame equivalent), versatile for landscapes, portraits, and everyday shooting.
Advanced optics: 17 elements in 11 groups, including 4 SLD and 4 aspherical elements, ensuring sharpness and reduced aberrations.
Video-friendly design: Inner zoom mechanism, minimal focus breathing, and quiet linear autofocus motor (HLA).
Close focus: Minimum focusing distance of 28cm, with 1:4.8 magnification at 40mm.
Durability: Dust- and splash-resistant, with water/oil-repellent coating on the front element.
Filter size: Standard 67mm thread for easy filter compatibility.
Lightweight: Fuji X mount, making it portable for travel and run-and-gun video.
Autofocus: Fast, precise, and quiet thanks to Sigma’s High-response Linear Actuator (HLA).
Image quality: Delivers prime-like sharpness even wide open at f/1.8.
Video use: Inner zoom keeps lens length constant, reducing balance issues on gimbals. Minimal focus breathing ensures smooth focus transitions.
Handling: Compact size and balanced weight make it suitable for handheld shooting and extended sessions.
The Sigma 17-40mm F1.8 DC Art (Fuji X) is a professional-grade zoom lens that combines the flexibility of a zoom with the image quality of a prime.
