Best-In-Class Performance

This lens incorporates two FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements. In addition, it effectively arranges three aspherical lenses, including a large-diameter aspherical lens to provide thorough correction of magnification chromatic aberration —encountered particularly in wide-angle lenses. This offers high resolution over the entire sensor, while sagittal coma flare is thoroughly corrected and distortion is also minimized to the fullest. Excellent performance is delivered in street photography, as well as shooting landscapes and night skies.

SIGMA Interchangeable Lenses for L-Mount

Along with the Announcement of L-mount Alliance, SIGMA is pleased to announce that the SIGMA 28mm F1.4 DG HSM Art Lens is now available for full-frame cameras in L-mount. These L-Mount series lenses have achieved high-speed AF and are fully compatible with AF-C mode, in-camera image stabilization, and in-camera aberration correction.

The Classical Angle Of View With The Latest Lens Design

28mm angle of view used to be a representative wide-angle in the era of film cameras, and attracts many fans even today. To accommodate the request from many photographers who expressed the strong interest in using the familiar 28mm with Art line quality, SIGMA produces the SIGMA 28mm F1.4 DG HSM | Art lens for L-mount, based on the know-how gained through development of the Art F1.4 prime lens lineup released so far. This newest traditional wide-angle lens, advantaged by the latest design and materials, as well as the processing technologies, is now available from SIGMA’s Art line.

Designed To Meet All Shooting Conditions

The water- and oil-repellent coating on the front lens element, together with the dust- and splash-resistant structure, ensures excellent performance even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.
