The Sigma 28mm F1.4 DG HSM I Art wide-angle lens stands out due to its thoroughly corrected magnification, chromatic aberration and sagittal coma flare, as well as its completely minimised distortion thanks – to its optical 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.
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.
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.
This lens features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring and cover connection, allowing photographers to work in all types of weather.

Features a hood with lock to prevent dropping the hood.
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.
The lens mount incorporates rubber sealing※ to protect the mount from dust and water drops.
* Except for SIGMA mount
The Canon mount version of this lens is compatible with the Canon Lens Aberration Correction function.* Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
* Function not available on all Canon cameras. Available corrections may vary depending on the Canon camera model.
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting.
* Functionality may be limited on some camera bodies.
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
