A new large-aperture F1.4 mid tele lens from the Contemporary line
This lens completes the Sigma large aperture series of portable wide-angle, standard, and telephoto prime lenses. Featuring compact design, light weight and outstanding image quality offered in Sigma’s Contemporary line, this lens stuns with a beautiful bokeh effect and the amount of brightness expected from F1.4 lenses even in the mid-telephoto range for cropped sensor cameras. In addition, this lens is characterized by smooth and quiet autofocus ideal for video shooting. By using the face recognition or eye AF functions of the camera, focus will continuously be on the face or the eye even if the subject moves during the shoot.
Offering an opportunity to experience the fun of shooting wide open, with F1.4 brightness
The first of the series is the standard lens 30mm F1.4 DC DN | Contemporary, and the second is the wide-angle lens 16mm F1.4 DC DN | Contemporary. The third addition is this smallest mid-tele lens in its class, 56mm F1.4 DC DN | Contemporary. 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 F1.4 lenses even in the mid-tele range. This addition completes the large aperture series comprised of portable wide-angle, standard, and telephoto lenses.
A member of the high-performance Contemporary line, featuring SIGMA’s latest technologies:
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. 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.
Mount with dust- and splash-proof construction
The mount features a special sealing to make the lens an excellent choice in a wide variety of 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.
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.
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.
Open aperture of F1.4
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.
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.
