I series 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 90mm 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 it was founded 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 to 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.

Especially compact even in the I series - wide-angle, standard, and mid-telephoto lenses in the lineup

New standards of optical performance for the Contemporary line

The Sigma 90mm F2.8 DG DN | Contemporary boasts exceptional optical performance with a ultra-high resolving power to match the latest high-resolution mirrorless cameras.

The lens is built using the very latest optical technology, and includes five SLD glass elements. This helps to reduce axial chromatic aberration that cannot be corrected in-camera, allowing the lens to achieve high resolution and clear image quality with no color bleeding. A high-precision glass molded aspherical lens provides both high resolution and beautiful bokeh. Photographers can enjoy shooting with soft, large bokeh without coloration and this is something that only a full-frame lens is able to deliver.

The lens also utilizes the camera’s optical correction functionality, which is an advantage of mirrorless systems, Sigma’s optical designers were therefore able to concentrate on correcting aberrations that can only be corrected by the optical design, thereby improving rendering performance and reducing the size and weight of the lens.

With a minimum focusing distance of 50cm and a maximum magnification ratio of 1:5, close-up macro-style photography is possible. The lens highlights the subject, allowing photographers to focus in on fine details or create more abstract compositions.

The AF drive system incorporates a quiet, high-speed stepping motor, making it suitable for still images as well as video recording.

Use of 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 that 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 lineup for professional cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use.

The 90mm F2.8 DG DN | Contemporary shares the same φ64mm maximum diameter and 55mm filter size ^＊1as the 24mm F3.5 DG DN | Contemporary and the 45mm F2.8 DG DN | Contemporary , making them a natural trio, especially for filmmakers who use filters more regularly. With a combined weight of only 735grams / 25.9oz. ^＊2, these three lenses (wide-angle, standard, mid-telephoto) can be used in tandem as part of a high-spec and compact camera system that covers a wide range of shooting situations.

*1 In addition to the 90mm F2.8 DG | Contemporary, I series lenses with a φ55mm filter thread include the 24mm F3.5 DG | Contemporary, 45mm F2.8 DG | Contemporary, and 17mm F4 DG | Contemporary (as of February 2025).

Magnetic metal lens cap

The I series lenses* are accompanied by a dedicated magnetic metal lens cap, in addition to a normal plastic cap. This dedicated metal cap clips to the front surface of the lens magnetically. It is no exaggeration to say that this meticulously crafted cap represents the finishing touch for the I series.

Magnetic metal lens cap holder LENS CAP HOLDER CH-11 (sold separately)

When a cap is removed from the lens it should have a proper place where it can be kept. Using this as a starting point, a cap holder using the magnetic force of the dedicated cap was created.
With the cap attached to the ring plate, and the plate clipped to a bag or belt, the cap is always within easy reach and is less likely to get lost. Plus, its elegant design is a stylish addition to a photographer’s equipment.

Inner focus system

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

Stepping Motor

The lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF.

Compatible with Lens Aberration Correction

Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.

*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON'(AUTO).

Super Multi-Layer Coating

SIGMA's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current SIGMA range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA's Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.
