The Sigma 30mm F1.4 DC DN Contemporary lens is a fixed maximum aperture standard prime lens for Sony E, Micro Four-Thirds, Canon EF-M, and Leica L mounts, announced by Sigma in February 2016.

It features a large manual focus ring and a detachable barrel-type lens hood.

The lens also excels in low-light photography given its fast maximum aperture of f/1.4, resulting in creamy smooth bokeh and thin depth‑of‑field.

[3] The lens suffers from moderate barrel distortion and minor vignetting when at f/1.4 (which can be resolved by stopping down to f/2.8).

Hints of chromatic aberration can be noted appearing in the corners of the frame when at f/1.4.
