24mm F3.5 DG DN

The I series SIGMA 24mm F3.5 DG DN | Contemporary brings exceptional detail and beautiful bokeh. Free your imagination with this incredible wide-angle prime for mirrorless cameras. 

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 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.

I series | A new photographic experience, "Premium Compact Primes" for mirrorless users

The SIGMA I series features full-frame-compatible lenses that offer mirrorless users a new and better alternative, both in the experience of shooting with the lens and in the impressive results it is able to achieve.

One of the key advantages of mirrorless cameras is their smaller form-factor, and this new 24mm optic is designed to be perfectly matched to these more compact systems without sacrificing performance. This combination of superb optical quality with exceptional portability, not previously possible with DSLR systems, will bring new opportunities to this and future generations of photographers.

Simultaneously, SIGMA is aware that, in this day and age when we have such huge diversity when it comes to what we use to photograph, as represented by smartphones, people look for something more than a mere act of "taking pictures" when they choose to own a camera and lenses.

SIGMA's excellence in development and processing technologies has been built up since its founding in 1961, and has become further sophisticated with the introduction of the SIGMA Global Vision in 2012. With this as a base, SIGMA has given careful thought how photographers use and enjoy their lenses, including optical design, advanced functionality, build quality and the experience of picking up and using the lens, and with all of this carefully considered, the I series was born.

Beautiful details and bokeh for every scene

The high resolving power of the 24mm F3.5 DG DN | Contemporary 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 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.

Use of multiple high-precision aspherical glass molded lenses

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.

Exceptional I series build quality with a compact form-factor

All I series lenses have an all-metal construction. The precision-cut aluminum parts not only give the barrel a sleek, stylish finish, but provide superb durability, which improves the quality of the entire product. Metal materials are also used in internal structures that slide with the operation ring for added robustness. These high-precision components crafted with SIGMA’s cutting-edge metalworking technology are also used in SIGMA’s cine lens line-up for professional cinematographers and provides an exquisite feel to touch as well as sound effects, making photographers want to reach for it and play with it over and over again.

With a pairing with the 45mm F2.8 DG DN | Contemporary in mind, the 24mm F3.5 DG DN | Contemporary is compatible with the same filter size of 55mm, with a matching outermost diameter and similar overall lengths. With a combined weight of only 440g / 15.5oz.*, these two lenses can be used in tandem as part of a high-spec and compact camera system that covers a wide range of shooting situations.
