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 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.
water- and oil-repellent coating
The front lens element incorporates 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.

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.
(*)Canon camera compatibility
The SGV interchangeable lens for Canon EF mount supports the "lens optical correction" installed in the following cameras.

※ For SGV interchangeable lenses released before 2017* , it is necessary that the lens firmware is updated to Ver.2.00 or later.
* The release year can be confirmed by the edition number (A017, C015, etc.) engraved on the lens barrel.
※After setting the Digital Lens Optimizer to [OFF], set the "Peripheral Illumination Correction", "Chromatic Aberration Correction", and "Distortion Correction" of the "Lens Aberration Correction" function to [ON] to achieve the appropriate corrections in accordance with the optical characteristics of each lens.
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.
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.

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.

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.
* 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

This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.
*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.

HSM (Hyper Sonic Motor)
The Hyper Sonic Motor (HSM) is an original SIGMA development that uses ultrasonic waves to drive the autofocus mechanism. Its extremely quiet operation helps avoid disturbing photographic subjects. High torque and speed assure rapid autofocus response. SIGMA uses two types of HSM: ring HSM and micro HSM. The Ring HSM configuration permits manual fine tuning of focus (manual override) by turning the focusing ring after autofocus is complete.
Rounded diaphragm
The polygonal shape of a conventional iris dia phragm causes out-of-focus light points to appear polygonal. A rounded diaphragm is designed to pro duce rounded out-of-focus light points when opened to near maximum aperture. This creates attractive bokeh effects in many situations, such as when pho tographing a subject against an out-of-focus surface of water from which light is being reflected.
Exclusive low-dispersion glass
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as "secondary spectrum" may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD ("F" Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.
