The SIGMA I-Series is a range of compact, beautifully designed high-performance lenses for mirrorless camera systems. The 90mm prime lens combines outstanding resolving power with a small body that is perfectly weighted for mirrorless systems.

The 90mm F2.8 DG DN Contemporary premium lens delivers outstanding optical performance, a large aperture of F2.8, an all-metal construction and is equipped with an aperture ring. It was developed from the ground up for mirrorless systems and is perfectly balanced in combination with modern full-frame cameras. Its high resolving power meets all the demands of the latest ultra-high megapixel camera models and

its versatile telephoto focal length is the longest focal length of the I-Series lenses to date, while remaining remarkably light and compact so that it can accompany you wherever you go in everyday life. It is optimized in every respect for use in mirrorless systems, focuses quickly and reliably with the autofocus and shines with its optical performance. Its pleasantly soft background bokeh makes it the ideal portrait lens and the close focusing distance of 50 cm allows photographers to get closer to their subject.

New optical performance standards
The optical design uses the most advanced technology, including five SLD lenses. This reduces the longitudinal color error that cannot be corrected in-camera, resulting in high resolution and clear detail without color fringing. At the same time, a precision-molded asphere ensures high contrast transfer of the finest details in the focus zone and a beautiful bokeh without color artifacts in the blurred background - a bokeh that only a full-frame lens can produce.

The lens is also designed with in-camera correction in mind. This strategy has allowed our lens designers to focus on correcting those aberrations that can only be corrected optically, improving overall imaging performance while reducing the size and weight of the lens.

With a close focusing distance of 50 cm and a maximum magnification of 1:5, macro shots are also possible.

Outstanding I-Series manufacturing quality
All I-Series lenses are all-metal constructions. The precisely manufactured aluminum components not only give the barrel a sleek and elegant finish, but also guarantee outstanding durability, which improves the quality of the entire product. Metal is also used for the internal construction, which provides additional robustness. These high-precision components, manufactured using innovative metal processing technology, are also used in cine lenses for professional filmmakers. Among other things, they ensure that the focus ring moves smoothly and that the aperture clicks into place almost silently, and this attention to haptics and ergonomics makes working with the lens a pleasure.

High-quality coating
An ideal lens directs the incident light through all the lenses and onto the sensor.

If, on the other hand, some of the light is reflected by individual lenses, not only is the light yield reduced; the reflections within the lens create ghost images and flare spots or reduce the contrast.

To prevent this, the 90mm F2.8 DG DN Contemporary uses a Super Multi-Layer Coating (SML), which reduces stray light and ghost images. The result is clear, sharp and high-contrast images without annoying lens flares.

For full-frame cameras
The 90mm F2.8 DG DN Contemporary is compatible with full-frame mirrorless cameras with L-mount.

A stepping motor is used for fast focusing. The autofocus with automatic eye detection used in newer mirrorless cameras is also supported, making precise focusing of portraits, for example, child's play.
