Sigma 17-40mm F1.8 DC | Art Lens for Sony E‑Mount
The Sigma 17-40mm F1.8 DC | Art is a groundbreaking standard zoom lens purpose-built for APS-C mirrorless cameras. With a constant F1.8 aperture and wide focal range, it combines prime-level brightness and flexibility in a portable design—ideal for photographers and videographers seeking creative depth and mobility.
Optical Performance
Constructed from 17 elements in 11 groups, including four SLD and four aspherical elements, this lens prioritises sharpness, contrast, and aberration correction even at its widest aperture. Advanced Super Multi-Layer Coating suppresses flare and ghosting, delivering vibrant, high-contrast images under all lighting conditions.
Aperture & Bokeh
The generous F1.8 maximum aperture across the full zoom range allows for exceptional low-light performance and smooth background blur. An 11-blade rounded diaphragm enhances creamy bokeh, rivaling equivalent prime lenses—a standout benefit for portrait and creative work.
Focal Range & Framing
Covering 17–40mm (≈25.5–60 mm full-frame equivalent) for Sony E-mount, this lens expands from wide-angle scenes to portrait-friendly mid-telephoto without changing lenses. It inherits Sigma’s inner zoom system for consistent handling and video-ready ergonomics.
Autofocus & Video Support
A fast, silent High-response Linear Actuator (HLA) autofocus system ensures quick, whisper-quiet focusing—ideal for vloggers and run-and-gun video operators. The design minimises focus breathing, ensuring smooth focus transitions in footage.
Build & Durability
Despite its bright aperture, the lens remains lightweight at just 525 g for Sony E-mount. A water- and oil-repellent front element and dust-and-splash resistant structure support outdoor shooting in variables conditions. A zoom lock prevents creep when carrying.
Control and Customisation
This Art-series lens features an aperture ring with click-stop and lock, two AFL buttons for custom functions, and an AF/MF switch. It is also USB Dock compatible, enabling firmware updates and calibration (via separate dock).
Compatibility
Designed for Sony E-mount APS-C cameras, the lens is available in multiple mounts including L, Fuji X, and Canon RF. Sony E versions began shipping in July 2025.
