High optical performance, F1.4 brightness, and compact enough to carry around every day With an easy-to-use angle of view of 35mm*, high optical performance, the brightness of a large F1.4 aperture, and a compact and lightweight lens body, SIGMA's experience accumulated in the Contemporary line has culminated in a lens that is ideal for use with APS-C mirrorless cameras. The lens offers excellent resolution from maximum aperture and the rich bokeh effects thanks to its F1.4 brightness. The lens demonstrates its descriptive power in a wide range of applications, including landscapes, portraits, and tabletop photography. In order to take advantage of the high mobility of mirrorless cameras, compactness of the lens body was also pursued. The SIGMA’s Contemporary lineup includes several compact and lightweight F1.4 prime lenses in the APS-C format, which are surprisingly compact to carry around. If you want to keep your equipment light and small, but not compromise on image rendering performance, this lens is sure to meet your needs, and will be a lens you will never want to let go. *35mm equivalent. Large aperture F1.4 brightness and excellent resolution from maximum aperture The SIGMA 23mm F1.4 DC DN | Contemporary has an easy-to-use angle of view equivalent to 35mm in 35mm format, as well as the brightness of a large F1.4 aperture and high descriptive power. The optics is composed of 13 elements in 10 groups, including 3 SLD glass elements and 2 aspherical lens elements, to achieve sharp, clear images. The lens delivers excellent resolving power from the maximum aperture. Furthermore, the large F1.4 aperture allows for large, beautiful bokeh effects. The compact, palm-size body allows you to enjoy the rich descriptive power of mirrorless cameras. Careful countermeasures against flare and ghosting enable clear shooting even in backlit environments. Large aperture F1.4 brightness and excellent resolution from maximum aperture Lens construction 13 elements in 10 groups with 10 SLD and 2 aspherical lens elements Inner focus system Compatible with high-speed autofocus Stepping motor Compatible with Lens Aberration Support DMF and AF+MF Super Multi-Layer Coating Mount with dust and splash resistant structure Designed to minimize flare and ghosting
Compact, lightweight and high-performance ultra-wide-angle 17mm lens with an impressive minimum focusing distance. “Compact, lightweight and high-performance ultra-wide-angle lens”. Using the latest technology, the 17mm had been created without compromise, despite its challenging design concept. Its wide-angle of view creates impactful landscape images with a unique perspective and, thanks to its minimum close focusing distance of 12cm, the lens can be enjoyed in a variety of alternative ways, including close-up photography and hand-held selfies. The optical design has been created exclusively for mirrorless camera systems, which helps reduce lens flare and ghosting that results in excellent image rendering. The all-metal lens barrel highlights SIGMA’s craftsmanship and attention to detail, making the SIGMA 17mm F4 DG DN | Contemporary a pleasure to use on every shoot. “Ultra-wide-angle lens" that matches the optical performance standards set by the SIGMA Contemporary line of lenses. The lens construction consists of two SLD glass elements and three aspherical lens elements. Aspherical lenses are used for both the front and rear optics. This not only keeps the size of the lens compact but also helps with correcting lens aberrations. As a result, the lens features a φ55mm filter thread (which is smaller than comparable lenses of similar focal lengths) which makes it easy to change filters between SIGMA I series lenses that share the same filter size. * Its construction also helps minimize flare and ghosting that is commonly found in ultra-wide-angle lenses, creating clear images in any environment. This is a lens with truly modern performance, thanks to the advanced processing and production technologies at SIGMA's only production facility in Aizu. *In addition to the 17mm F4 DG DN | Contemporary, I series lenses with a φ55mm filter thread include the 24mm F3.5 DG DN | Contemporary, 45mm F2.8 DG DN | Contemporary, and 90mm F2.8 DG DN | Contemporary (as of April 2023). A highlight of using the 17mm is the impressive minimum focusing distance of 12cm. Capture close-up macro style images in remarkable detail with expansive backgrounds. It is also suitable for selfies and vlogging, where items need to be shown at an arms-reach. A quiet, high-speed stepping motor drives the AF delivering fast and accurate results in both stills and video. Ultra wide in sight. Tiny in size. Lens construction: 9 elements in 8 groups with 2 SLD and 3 aspherical lens elements Inner focus system Compatible with high-speed autofocus Stepping motor Support DMF and AF+MF Aperture Ring Focus mode switch Mount with dust and splash resistant structure Designed to minimize flare and ghosting
