The SIGMA I series introduces compact, beautifully designed, high-performance optics for mirrorless camera systems. In its first collection, SIGMA introduces a 24mm wide-angle prime lens to the Contemporary lens line-up that offers excellent portability and versatility. The all-new 24mm F3.5 DG DN | Contemporary lens for L-mount offers a very compact design similar to that of the 45mm F2.8 DG DN | Contemporary. Despite its small size, there is no compromise on performance –it is capable of capturing the finest details as required when shooting on high resolution full-frame cameras. With a very short minimum focus distance of around 10cm and a maximum reproduction ratio of 1:2, it enables photographers to shoot more freely, without worrying about the distance between the lens and the subject. The robust and stylish I series lens body finish brings a more satisfying shooting experience. The 24mm F3.5 DG DN | Contemporary is a versatile prime that will become an extension of your creative vision.
The lens features the latest optical design optimized for mirrorless systems. This includes high-precision, glass-molded aspherical elements created with advanced processing technology, and SLD glass and high refractive index glass elements. Together they make it possible to combine high optical performance with compactness. In addition, the smooth focus drive system designed around a quiet and fast stepping motor also makes the 24mm F3.5 DG DN | Contemporary a desirable choice for shooting video.
The surface of molds for glass molding, which is a process that forms optical components by pressing glass materials at high temperatures, requires ultra-high precision. SIGMA uses high-precision molds whose surfaces are controlled with an accuracy of ±5 nanometers (0.000005 mm) or smaller. High precision aspherical glass molded lenses archives both good aberration correction and compact lens size.
The high resolving power of the 24mm F3.5 DG DN | Contemporary lens for L-mount covers the entire image from the center to the edges, which means photographers can rely on edge-to-edge sharpness at all apertures when shooting wide-angle scenes. With a minimum focus distance of around 10cm and a maximum reproduction ratio of 1:2, it enables photographers to explore a subject more freely, from capturing distant landscapes to photographing close-ups of smaller objects. In addition to the attractive bokeh, it also gives photographers near-circular out-of-focus highlights, even at the edges of the frame. This helps create a close-up image of an in-focus subject with a blurred background, a technique that is very useful in a variety of settings.
The lens is accompanied by a dedicated magnetic metal lens cap that clips to the front surface of the lens magnetically.
