Sigma 30mm f/1.4 DC DN Contemporary Lens (Sony E)

The Sigma 30mm f/1.4 DC DN Contemporary Lens (Sony E) is a fast, exceptionally versatile normal-length prime lens engineered for APS-C-format Sony E-mount mirrorless cameras, delivering a highly useful 45mm equivalent focal length that bridges the gap between wide and short-telephoto perspectives. It’s a perfect choice for street photography, portraiture, documentation, and everyday shooting, holding the distinction of being the first affordable f/1.4 performance lens for the mirrorless market at its release.

Optically, the lens is built from 9 elements in 7 groups, including two aspherical elements and one high-refractive index element, significantly reducing spherical aberrations and distortion for increased clarity and definition. Sigma’s Super Multi-Layer Coating minimizes lens flare and ghosting for contrast-rich, color-neutral images even in backlit conditions, and a rounded 9-blade diaphragm, paired with the bright f/1.4 maximum aperture, offers extensive control over depth of field at a 50.7-degree angle of view.

Autofocus is handled by a fast, smooth stepping motor designed to support video as well as stills, delivering quiet, confident focus acquisition. The lens has a minimum focusing distance of 11.8 in. (30cm), yielding a maximum magnification ratio of approximately 1:7.

Build quality combines a lens barrel and aperture components made of Sigma’s Thermally Stable Composite (TSC) material, contributing to a compact form factor and smooth aperture operation. The lens measures approximately 2.6 x 2.9 in. (64.8 x 73.3mm) and weighs approximately 9.3 oz. (265g), and accepts a 52mm filter thread. It does not include optical image stabilization, and ships with a lens hood.

As an APS-C-specific lens, the Sigma 30mm f/1.4 DC DN Contemporary is designed exclusively for Sony’s APS-C E-mount mirrorless cameras and does not cover a full-frame image circle.
