KEY FEATURES

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 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.

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, 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.

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 line-up for professional cinematographers and provide a tactile, ergonomic feel that make the lens a pleasure to use.

The 90mm F2.8 DG DN | Contemporary also shares the same 64mm maximum diameter and 55mm filter size as the 24mm F3.5 DG DN | Contemporary and 45mm F2.8 DG DN | Contemporary lenses, making them a natural trio, especially for filmmakers who use filters more regularly.
