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.

New standards of optical performance

The SIGMA 90mm f/2.8 DG DN | Contemporary boasts exceptional optical performance with an 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 colour bleeding. A high-precision glass-moulded aspherical lens provides both high resolution and beautiful bokeh. Photographers can enjoy shooting with soft, large bokeh without colouration 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 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.
