The light-sensitive standard lens Sigma 30 mm F1.4 DC DN Contemporary allows users of mirrorless cameras to shoot with a maximum aperture of F1.4. Particularly appealing are the beautiful bokeh that can only be achieved with a fast lens and the exceptionally precise optical performance that characterizes a top-class prime lens. These technologies and design considerations, which are characteristic of the Contemporary product line concept, are well balanced in this lens.

A prime lens that offers a field of view similar to that of the human eye with an approximate focal length of 50 mm and a brightness of F1.4. The shallow depth of field at full aperture provides photographers with ideal conditions for captivating portraits and still lifes. For landscape shots or snapshots, a smaller aperture with greater depth of field can be chosen. Standard lenses offer a wide range of photographic applications and have therefore been a staple for photographers for decades.

This standard lens provides a 35 mm equivalent focal length of 60 mm on the Micro Four Thirds system and 45 mm on the Sony E-Mount or Canon EF-M system. Sigma lenses labeled "DC" offer optimal performance on cameras with APS-C image sensors. Using a DC lens on a camera with a full-frame image sensor inevitably leads to vignetting. For optimal results, the active image area of the sensor should be adjusted to the image circle of the lens. Sigma lenses labeled "DN" provide optimal performance in conjunction with cameras that have a short flange distance.
