The Sigma 16mm F1.4 DC DN | Contemporary is the world's first interchangeable lens for Sony E-Mount mirrorless cameras with APS-C format sensors, offering a field of view equivalent to a 24mm focal length in 35mm full-frame format and a maximum aperture of F1.4. In the Micro Four Thirds mount, the lens's field of view corresponds to a 32mm focal length in 35mm full-frame format, also providing an aperture value of F1.4. It is the high-aperture wide-angle lens that photographers with mirrorless cameras have been waiting for.

The DN lenses for mirrorless cameras are characterized by a lightweight, compact design developed for everyday use, delivering outstanding performance across all key focal lengths. The 16mm F1.4 DC DN Contemporary builds on the success of the 30mm F1.4 DC DN Contemporary, which Sigma released in 2016 as the first lens in a new series of prime lenses for mirrorless cameras. It combines the brightness of F1.4 with optical excellence.

The 16mm F1.4 DC DN Contemporary, which shares the same development concept as the Sigma 30mm F1.4 DC DN Contemporary, features a lens construction of 16 elements in 13 groups and is made from high-quality materials. This lens effectively minimizes optical aberrations and delivers excellent resolution even at wide open apertures and throughout the entire aperture range. The lens design and stepping motor also provide smooth autofocus during video recording, and the mount is dust and splash resistant due to a sealing.
