Sigma 35mm f/2 DG DN Contemporary Lens for Sony E

Professional-level performance in a compact package,
bringing you new creative possibilities.

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.

The 35mm F2 DG DN | Contemporary, a classic wide standard prime which photographers would not want to compromise on, comes with a maximum aperture of F2, and offers both compactness and high optical performance. Its modest size and weight make it portable enough to be carried around in a small kit bag for day-to-day shooting, but owing to its outstanding optical quality, wide aperture, and the high quality constructed body which is guaranteed for the I series, it is equally comfortable being used for a professional photo such as night sky photography and video works. This all-new wide standard lens is designed for photographers who value the experience of taking a picture just as much as the quality of the results.

New standards of optical performance
for the Contemporary line

The 35mm F2 DG DN | 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-moulded 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 DN | Contemporary offers consistent, high resolving power right across the frame.

Use of multiple high-precision aspherical glass moulded lenses

The surface of moulds for glass moulding, which is a process that forms optical components by pressing glass materials at high temperatures, requires ultra-high precision. SIGMA uses high-precision moulds whose surfaces are controlled with an accuracy of ±5 nanometers (0.000005 mm) or smaller. High precision aspherical glass moulded lenses archives both good aberration correction and compact lens size.

Exceptional I series build quality
with a compact form-factor

All I series lenses have an all-metal construction. The precision-cut aluminium parts not only give the barrel a sleek, stylish finish but provide superb durability, which 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 provides an exquisite feel to touch as well as sound effects, making photographers want to reach for it and play with it over and over again.

 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 1covering functions as a finger hold when attaching or detaching the lens.
