The first of the series is the standard Sigma 30mm F1.4 DC DN Contemporary Lens, and the second is the wide-angle Sigma 16mm F1.4 DC DN Contemporary Lens. The third addition is this smallest mid-tele lens in its class, Sigma 56mm f/1.4 DC DN Contemporary Lens. 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.
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. And now control algorithm including AF drive and communication speed optimization has been developed specifically for X Mount interchangeable lenses.
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.
