The new SIGMA 16mm F 1.4 DC DN / Contemporary is the world's first interchangeable lens for mirrorless Sony E-mount cameras in the APS-C format to offer a 24mm focal length (35mm equivalent) and F 1.4 brightness. The lens for Micro Four Thirds offers a 32mm focal length (35mm equivalent) with the same f-number of 1.4. This is the large-diameter wide-angle lens for which mirrorless camera users have been waiting. Developed to feature a lightweight, compact package for everyday use, SIGMA DN lenses for mirrorless cameras deliver superior performance covering the key focal lengths.

The new lens builds on the success of the 30mm F 1.4 DC DN / Contemporary, which SIGMA released in 2016 as the first in a new series of prime lenses for mirrorless cameras. The 16mm F 1.4 DC DN / Contemporary also combines F 1.4 brightness with top-level optical performance. Sharing its development concept with the SIGMA 30mm F 1.4 DC DN / Contemporary, the 16mm F 1.4 DC DN / Contemporary features a lens structure with 16 elements in 13 groups and includes the finest materials. This lens effectively minimizes optical aberrations and offers superb resolution at wide-open aperture and throughout the aperture range.

The optical design and stepping motor deliver smooth autofocus during video shooting, while the mount features a special sealing for a dust- and splash-proof design.
