A large-aperture f/1.4 mid tele lens from the Contemporary line, Sigma 56mm f/1.4 DC DN Prime Lens offers an opportunity to experience the fun of shooting wide open with f/1.4 brightness. While retaining the compact, lightweight, and outstanding image quality concepts of the Contemporary line, thanks to Sigma’s leading-edge technology, this lens provides the amount of bokeh and admirable brightness expected from f/1.4 lenses even in the mid-tele range. This addition completes the large aperture series comprised of portable wide-angle, standard, and telephoto lenses.

Smallest Mid-Tele Lens in Its Class

The smallest mid-tele lens in its class, the Sigma 56mm f/1.4 Contemporary DC DN Prime Lens is the third addition to the f/1.4 series following the 30mm and 16mm lenses. While retaining the compact, lightweight, and outstanding image quality concepts of the Contemporary line, thanks to Sigma’s leading-edge technology, this lens provides the amount of bokeh and admirable brightness expected from f/1.4 lenses even in the mid-tele range. This addition completes the large aperture series comprised of portable wide-angle, standard, and telephoto lenses.

Impressive Construction

The Sigma 56mm f/1.4 DC DN Contemporary features 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.

Compatibility

Sigma lenses with DC in the name are designed for optimal performance on cameras with APS-C image sensors. When a DC lens is used with a camera with a full-frame image sensor, vignetting will occur. Photographers are advised to adjust image area settings for optimal image results. Sigma lenses with DN in the name are designed for optimal performance on cameras with a short flange back distance.

Beautiful Bokeh

The lens benefits from an open aperture of f/1.4 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.

Fast Hybrid AF

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.
