The Sigma 35mm F2 DG Contemporary Lens in Black for L Mount is a full-frame compatible lens that offers new value to mirrorless systems. The combination of superb optical performance with a level of compactness that is perfectly suited to smaller and lighter modern mirrorless cameras will bring you new opportunities for a perfect shot.

Optical Performance for the Contemporary Lens

The 35mm F2 DG Contemporary brings to the table the highest level of optical performance at a maximum aperture of F2 with a lens body of a size that matches a mirrorless system. Axial chromatic aberration, a point of particular concern with a bright lens, is corrected with SLD glass, while an optimal 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, which were 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 cutting edge optical design and advanced processing technology, the 35mm F2 DG Contemporary offers consistent, high resolving power right across the frame.

Multiple 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 plus and minus 5 nanometers (0.000005 mm) or smaller. High-precision aspherical glass molded lenses archive both good aberration correction and compact lens size.

Exceptional Build Quality with a Compact Form-Factor

It has 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.

Cover Ring

The cover ring between the focus ring and the aperture ring has hairline processing that is also used for the rear cylinder of the Art line. This covering functions as a finger hold when attaching or detaching the lens.

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.

Magnetic Metal Lens Cap

The lens is 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 to the lens.

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.

Super Multi-Layer Coating

Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections within the lens. In digital cameras, flare, and ghosting may also be caused by reflections between the image sensor and lens surfaces. Multi-layer coating is highly effective, assuring images of outstanding contrast.

Aperture Ring and Focus Mode Switch

Aperture ring is designed to help users work intuitively. Using this switch, it is possible to switch the focus mode between AF and MF.
