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, 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.
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.
Designed to meet all shooting conditions
The water- and oil-repellent coating on the front lens element, together with the dust- and splash-proof 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.
water- and oil-repellent coating
Forefront and rear lenses incorporate a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.
dust- and splash-proof structure
This lens features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather.
The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures instantaneous photography movement.
Hood with lock
Features a hood with lock to prevent dropping the hood.
Manual override (MO)
Manual override (MO) capable of switching two full-time manual modes
* By setting it to the MO position, it switches to manual focus by rotating the focus ring even during continuous AF.
The default setting of Full-time MF function varies for each mount.
