Sigma 17-40mm F1.8 DC | Art Lens for Fuji X Mount

The Sigma 17–40 mm F1.8 DC | Art lens for Fujifilm X‑Mount revolutionises APS‑C mirrorless zooms by offering a constant F1.8 aperture across a versatile focal range. Lightweight, rugged and video-ready, this zoom delivers prime-like clarity without swapping lenses—perfect for travel, street, portraits and cinematic content creators.

Optical Performance & Clarity

Built from 17 elements in 11 groups—including four SLD and four aspherical elements—this lens delivers exceptional sharpness, contrast and aberration control even at its widest aperture. Sigma’s Super Multi-Layer Coating effectively suppresses flare and ghosting to deliver crisp images under challenging light.

Aperture & Bokeh

With a constant F1.8 aperture, the lens enables superb low-light performance and depth-of-field control. Its 11-blade rounded diaphragm crafts smooth, attractive bokeh, ideal for portraits or subject isolation with a cinematic feel.

Range & Handling

Offering a 17–40 mm range (≈25.5–60 mm full‑frame equivalent), this zoom replaces multiple primes while keeping weight and bulk to a minimum. The internal zoom mechanism keeps the barrel length constant, preserving balance, sealing, and suitability for gimbals or tripods.

Autofocus & Video Features

The High‑response Linear Actuator autofocus provides fast, quiet focusing with minimal focus breathing—essential for clean focus pulls in video. Built-in AFL buttons and a de-clickable aperture ring offer tactile control for filmmakers.

Build Quality & Weather Resistance

At just 535 g and 73 × 116 mm, this lens is highly portable. It also boasts dust- and splash-resistant construction, plus a water- and oil-repellent front element—ideal for outdoor and travel use. A zoom lock helps prevent lens creep during transport.
