A stunning wide-standard prime offering professional performance in a compact body.

The SIGMA I series introduces compact, beautifully designed, high-performance optics for mirrorless camera systems. In its first collection, SIGMA introduces a versatile 35mm prime lens to the Contemporary line-up, which combines excellent resolving power with a small body that is perfectly weighted for mirrorless systems.

This all-new I series model is portable enough to be carried around in a small kitbag for day-to-day shooting, but owing to its outstanding optical design, impressive build quality, F2 aperture and smooth focus drive system with a quiet and fast stepping motor, it is equally well-suited to heavy professional use. The lens is ideal for street and astro photography, environmental portraits, weddings and video. It is designed for photographers and film makers who value the experience of taking a picture just as much as the quality of the final result.

New standards of optical performance for the Contemporary line

Despite its small size, no compromise has been made on the optical performance of the SIGMA I series 24mm F3.5 DG DN | Contemporary. It is capable of capturing the finest details when shooting on high resolution full-frame cameras, and it does so across the entire frame, which means photographers can rely on edge-to-edge sharpness at all apertures when shooting wide-angle scenes.

The 35mm F2 DG DN | Contemporary brings to the table the highest level of optical performance even at its maximum aperture of F2. Axial chromatic aberration, a point of particular concern with a bright lens, is corrected with SLD glass. The placement of high-refractive index elements provides effective correction of various types of aberration, while keeping the amount of glass used to a minimum.

The use of three high-precision glass-molded aspherical lenses was made possible thanks to advanced production technology at the Aizu factory, SIGMA’s only production site. These elements provide correction of spherical aberration and field curvature, and the fluctuation of aberration at the time of focusing. The lens design also provides a very good correction of sagittal coma aberration, making it capable of capturing details fine enough for it to be used for night sky photography.

Thanks to SIGMA’s cutting-edge optical design and advanced processing technology, the 35mm F2 DG DN | Contemporary offers consistent, high resolving power right across the frame.

The lens renders very attractive bokeh, and out-of-focus highlights are near-circular, even at the edges of the frame.

Stunning optics with minimal flare and ghosting

The 35mm F2 DG DN uses exceptionally high quality, high refractive index glass, including three precision moulded aspherical elements and one SLD element, in order to keep images pin sharp and flare and ghosting to a minimum. This ensures very bright points of light remain well-controlled.

Ultra-high lens resolution for capturing very fine detail
