Sigma 35mm f2 DG © L-Mount silver

Due to its modest size and light weight, it is portable enough to carry around in a small bag for everyday shooting, but due to its excellent optical quality,

large aperture

and

high quality construction guaranteed for the I-series

, it is

just as comfortable

for

professional

photography

as it is

for

night sky photography and video work

.The excellent optical quality, wide aperture and high quality construction guaranteed for the I-series make it just as comfortable for professional photography as it is for night sky photography and video work. This brand new standard wide-angle lens is designed for photographers who value the experience of shooting as much as the quality of the results.

New standards in optical performance for the Contemporary line

The 35mm F2 DG Contemporary offers the highest level of optical performance at a maximum aperture of F2 with a lens body as large as a mirrorless system. Axial chromatic aberration, a point of particular importance in a fast lens, is corrected with SLD glass, while optimal placement of high refractive index elements enables effective correction of various types of aberrations while minimizing the amount of glass used. The use of three high-precision glass-molded aspherical lenses made possible thanks to advanced production technology at the Aizu plant, Sigma's only production site. These elements ensure the correction of spherical aberration and field curvature as well as the fluctuation of aberration at the time of focusing. The lens design also provides very good correction of sagittal coma aberration, so it is able to capture details fine enough to be used for night sky photography

. Thanks to the state-of-the-art optical design and advanced processing technology, the 35mm F2 DG Contemporary offers consistent, high resolving power across the entire frame.

Use of multiple high-precision aspherical glass mold lenses

The surface of molds for glass molding, a process in which optical components are formed by pressing glass materials at high temperatures, requires extremely high precision. Sigma uses high-precision tools whose surfaces are controlled to an accuracy of ±5 nanometers (0.000005 mm) or less. High-precision aspherical glass mold lenses ensure both good aberration correction and a compact lens size.

Stepping motor

The lens enables smooth, quiet and fast autofocus enabled by a stepping motor and supports face/eye detection AF as well as video AF.

Mount with dust and splash-proof structure

The lens mount is equipped with a rubber seal that protects the mount from dust and water droplets

. Super Multi-Layer Coating

Sigma's proprietary Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections in the lens. All lenses in the current Sigma range are equipped with this original technology. With digital cameras, stray light and ghost images can also be caused by reflections between the image sensor and the lens surfaces. Here too, the Super Multi-Layer Coating of Sigma is highly effective and ensures images with excellent contrast.

Aperture ring

Aperture ring for intuitive operation.

Focus mode switch

This switch allows you to switch the focus mode between AF and MF.

Linear focus / Non-linear focus (only for L-mount）

A method of focus movement of interchangeable lenses for mirrorless cameras (DN lens) in relation to the rotation angle of the focus ring when focusing manually. With "non-linear focusing", the extent of the focal point movement varies depending on the rotational speed of the focus ring. With linear focusing, the amount of focal point shift remains the same regardless of the rotational speed of the focusing ring if the angle of rotation of the focusing ring is the same.

High-precision, robust brass bayonet mount

The brass mount combines high precision with a robust design. The treated surfaces and increased strength contribute to the exceptional durability of the lens.

Rounded aperture

The polygonal shape of a conventional iris diaphragm makes out-of-focus points of light appear polygonal. A rounded iris creates rounded out-of-focus points of light when it is opened almost to the maximum aperture. This creates attractive bokeh effects in many situations, e.g. when photographing a subject in front of a blurred water surface from which light is reflected.
