The Sigma 28mm f1.4 DG HSM Art lens offers impressive versatility and unrivalled optical quality in a popular fixed focal length. As with all of Sigma's Art line of lenses, the 28mm f1.4 retains edge-to-edge sharpness across the entire frame, at all apertures. 9 rounded aperture blades create a smooth, desirable bokeh in the out-of-focus areas, while the inclusion of a Hyper Sonic Motor also ensures fast, silent autofocus, although full-time manual override is available as well.

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.

Incorporating two FLD ("F" Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements. In addition, three aspherical lenses, including a large-diameter aspherical lens provide thorough correction of magnification chromatic aberration encountered particularly in wide-angle lenses.

Designed to minimize flare and ghosting
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.

Mount with dust- and splash-proof construction
The lens mount incorporates rubber sealing to protect the mount from dust and water drops.

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.
