Smooth AF ideal for video shooting
The combination of optical design for video AF and use of the stepping motor enables smooth and quiet autofocus. This lens is also compatible with the Sony E-mount Fast Hybrid AF, achieving precise AF tracking. By using the face recognition or eye AF functions of cameras, focus will continuously be on the face or the eye even if the subject moves during the shoot.
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.
Mount with Dust and Splash Resistant Structure
The mount features a special sealing* to make the lens an excellent choice in a wide variety of conditions.
* Except for Canon EF-M mount
Impressively compact construction with image quality rivaling Sigma's Art line.
To achieve such a compact construction, lens design is considered based on the capabilities of the camera body function to correct* peripheral light amount and distortion. Moreover, axial color aberration, which is difficult to eliminate by image processing, is efficiently corrected by incorporating an SLD glass element. A compactness and lightweight construction combined with superb image quality is achieved.
* Limited to what the camera supports.

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. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
The only three F1.4 AF lens system for APS-C Sony E-mount mirrorless cameras
The lens benefits from an open aperture of F1.4 to achieve sufficient amount of bokeh and admirable brightness even with APS-C size cameras which tend to have smaller bokeh effects compared to 35mm full size systems. Its compact and lightweight body is perfect for daily use, capable of capturing various scenes ranging from portraits to snapshots, as well as night view.
Rounded diaphragm
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
Sigma DC DN SERIES
Over the years, Sigma has built an extensive lineup of bright prime lenses ranging from wide-angle to telephoto. Now, for mirrorless cameras, Sigma is developing a range of interchangeable lenses that feature a lightweight, compact package for convenient daily shooting while delivering superior performance and covering the key focal lengths.
Developed to feature a lightweight, compact package for everyday use, Sigma DN lenses for mirrorless cameras deliver superior performance covering the key focal lengths. The new lens builds on the success of the 30mm F1.4 DC DN | Contemporary, which Sigma released in 2016 as the first in a new series of prime lenses for mirrorless cameras. The 16mm F1.4 DC DN | Contemporary also combines F1.4 brightness with top-level optical performance.
The first in this Sigma series of prime lenses for mirrorless cameras was the standard prime 30mm F1.4 DC DN | Contemporary, then the wide-angle prime 16mm F1.4 DC DN | Contemporary, and now followed by the telephoto 56mm F1.4 DC DN | Contemporary, Sigma has made a new and complete system for mirrorless camera users.

Compatible with Lens Aberration Correction
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 available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON'(AUTO).
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.
Mount with Dust and Splash Resistant Structure
The lens mount incorporates rubber sealing to protect the mount from dust and water drops.
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.
