Overview

The Sigma 30mm f/2.8 EX DN is a high-performance standard lens designed exclusively for mirrorless interchangeable lens cameras and has the equivalent angle of view as a 60mm lens (35mm equivalent focal length) on the Micro Four Thirds systems and 45mm (35mm equivalent focal length) on the E-mount system.

Two glass mold aspherical lenses, including a double-sided aspherical lens, provide excellent correction for all types of aberration. The inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal distance. Sigmas Super Multi-Layer Coating reduces flare and ghosting as well as provides sharp and high contrast images even at the maximum aperture. The superior telecentric optical design improves the image quality throughout the frame. The optical design also allows the lens to be compact and lightweight. This lens benefits from a newly developed linear AF motor which moves the lens elements directly without the need for gears or the drive of other mechanical parts. This system ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos. The lens features a rounded 7 blade diaphragm creating an attractive blur to the out of focus areas of the image. This Sigma 30mm F2.8 EX DN has a minimum focusing distance of 30cm/11.8in and a maximum magnification ratio of 1:8.1.

Please note that due to the type of focusing mechanism, when not mounted to a camera body a rattling within the lens is a common and normal occurrence.

Elements / Groups: The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs. View All Attribute Definitions
