The most-anticipated lens for wide-angle prime enthusiasts, now available from SIGMA’s Art line.
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.

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.

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.

High-speed AF
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

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

SIGMA’s industry-leading wide-angle collection
With the launch of this lens, the lineup of large-diameter wide-angle prime lenses compatible with 35mm full-frame has expanded to five, ranging from 14mm to 35mm. All lenses except for 14mm have an F1.4 brightness (F1.8 for 14mm), enabling photographers to choose the angle of view that best suits them, process attractive bokeh in the background, and capture their imagination.

Compatible with Canon Lens Aberration Correction
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.}

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.

Nikon electromagnetic diaphragm mechanism included
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.
^{Note: Functionality may be limited on some camera bodies.}

High-precision, rugged brass bayonet mount
The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.

Rounded diaphragm
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

Compatible with full-frame Sony E-mount cameras
The version of this lens compatible with Sony E-mount mirrorless cameras contains the same optical system as for SLRs. SIGMA MOUNT CONVERTER MC-11 is not required, as the lens performs the same functions as the converter, including in-camera image stabilization and in-camera lens aberration correction. In addition, the lens is compatible with Sony’s Continuous AF, which is not addressed by MOUNT CONVERTER MC-11.
^{Note: This product is developed, manufactured and sold based on the specifications of E-mount which was disclosed by Sony Corporation under the license agreement with Sony}
