– Beautiful rendering and bokeh, and the ability to get as close as you want Wide-angle lenses that can be freely enjoyed in all scenes
The “I Series” lenses challenge new values as interchangeable lenses for the mirrorless era. From the first phase of this series, we propose a wide-angle single focal length lens with high mobility that can be used in a wide range of shooting situations.
Following the 45mm F2.8 DG DN Contemporary, SIGMA has achieved the highest level of compactness among its full-frame lenses. Without compromising on performance, it has the high descriptive performance required for full-frame photography. Furthermore, with a minimum focusing distance of approximately 10 cm and a maximum magnification of 1:2, it allows photographers the freedom to shoot without being restricted by the distance to the subject.
The I-series lens body finish, which is designed to satisfy lens owners, also makes this lens the highest-quality everyday lens available for enjoyable shooting in all situations.

– I-series lenses offer new value as “premium compact primes” for mirrorless systems
The I Series is a series of full-frame compatible lenses that offers new value to mirrorless systems. One of the major advantages of mirrorless systems is that they are compact and lightweight. The combination of high optical performance and compactness, which was not possible with SLR cameras, creates new opportunities for photographers.
On the other hand, Sigma believes that in this day and age, when the means of photography have become so diverse, including mobile devices, owning a camera and lenses requires more than just the act of “taking a picture.
The “I-series” lenses are the result of careful consideration of the quality of the lens as a tool, the feel of the lens when handling it, and the pleasure of owning it, all based on the high development and processing technologies accumulated since the company’s founding in 1961 and refined through the SIGMA GLOBAL VISION in 2012. The SIGMA Contemporary answers the question of what kind of value can be proposed for the existence of lenses today.

– Beautiful rendering and bokeh that can be enjoyed in all scenes
With the 24mm F3.5 DG DN Contemporary, you can enjoy wide-angle photography that makes the most of the 24mm angle of view thanks to its high resolving power from the center to the periphery of the image. With a minimum focusing distance of approximately 10 cm and a maximum magnification of 1:2, you can enjoy shooting everything from distant landscapes to close-up shots on a table.
In addition to beautiful, straightforward bokeh, the lens produces a near-circular bokeh effect even at the periphery of the image, making it possible to get close to the subject while blurring the background, a useful feature in a variety of situations, from tabletop photography to snapshots.
The lens achieves both high optical performance and compactness through the latest optical design technology optimized for mirrorless systems, high-precision glass-molded aspherical lenses made possible by advanced processing technology, and the appropriate use of SLD glass and glass with a high refractive index. Furthermore, smooth focus drive by a quiet and fast stepping motor is also suitable for movie shooting.

– Build quality of I-series specifications
The I-series cameras share the same metal exterior. The machined aluminum parts are not only beautiful, but also enhance the quality of the product itself, such as its solid rigidity and high durability. Furthermore, metal materials are also used for internal parts in appropriate places. High-precision parts made possible by advanced metalworking technology backed by the SIGMA CINE LENS, a professional-use lens dedicated to imaging, provide each control part with a superb feel and tone that makes you want to operate it over and over again.
The combined weight of the 45mm F2.8 DG DN Contemporary and the two lenses is 440 grams*, making it possible to use both lenses in a variety of photographic situations. Together, the two lenses can create a high-specification, compact photographic system that can be used in a variety of photographic situations.
