Sigma AF 17-40mm F1.8 DC (A) Lens - L-Mount

Engineered for Excellence in the L-Mount Ecosystem

Optimized for L-Mount mirrorless systems, the Sigma 17-40mm F1.8 DC | Art delivers professional-grade performance for creators seeking a fast, standard zoom with a cinematic visual language. It’s the ideal tool for photographers and filmmakers using Leica, Panasonic, or SIGMA APS-C bodies who demand unmatched clarity, depth, and control across a highly practical zoom range.

Consistent F1.8 Aperture, Uncompromising Detail

From dramatic wide-angle scenes to tight environmental portraits, the lens maintains a constant F1.8 aperture, empowering users to capture shallow depth of field and work effectively in low light. High-precision aspherical and SLD elements reduce chromatic aberrations and coma flare, enabling razor-sharp detail and vibrant colour rendition even when shooting wide open.

Precision Mechanism for Hybrid Creators

This L-Mount version is fully compatible with SIGMA’s USB Dock UD-11, offering advanced customization of focus behaviour. Whether you prefer linear or non-linear manual focus feel, you can tailor the lens to your shooting style. The inner zoom mechanism improves balance on gimbals and sliders, and the two customizable AFL buttons provide intuitive control during both photo and video work.

Designed for the Demands of the Field

Weighing just 535g and built with weather-resistant sealing, the 17-40mm F1.8 DC | Art combines portability with resilience. Its fluorine-coated front element resists oil and water, making it suitable for field assignments where environmental reliability is essential.
