Sigma's ultra-wide APS-C prime, a fast and sharp lens available in multiple mirrorless mounts.
The Sigma 16mm f/1.4 DC DN Contemporary is a fast ultra-wide prime designed for APS-C and Micro Four Thirds mirrorless cameras. Launched in 2017, it provides a 24mm equivalent on APS-C or 32mm on MFT. It quickly became one of the most popular third-party primes for compact mirrorless systems, praised for delivering fast-aperture quality at an affordable price.
Optical quality is excellent with very good sharpness from f/2 onwards and usable results wide open at f/1.4. Chromatic aberration is well controlled. Bokeh at f/1.4 is smooth and pleasant for a wide-angle lens. Autofocus via a stepping motor is fast, accurate, and near-silent. Build is a combination of metal and quality plastic with a solid feel.
Available in Sony E, Fujifilm X, Canon EF-M, L-Mount, Micro Four Thirds, and Nikon Z mounts. Filter thread is 67mm. Each mount version is optically identical. Part of Sigma's DC DN Contemporary line designed specifically for mirrorless. The 16mm f/1.4 pairs naturally with the Sigma 30mm f/1.4 and 56mm f/1.4 DC DN to form a popular three-prime kit.
Good value used across all mount options. Check autofocus accuracy, front element condition, and mount contacts. The lens performs consistently well across copies. An outstanding choice for astrophotography, environmental portraits, and vlogging. One of the best third-party APS-C primes available.
