The Sigma 16mm f/1.4 DC DN Contemporary is a prime lens for APS-C mirrorless cameras with a Sony E mount. It has a 24mm focal length (35mm equivalent) and an f/1.4 maximum aperture. The large aperture suits low light and shallow depth of field.
The lens has 16 elements in 13 groups. The optical design is meant to minimize optical aberrations and to resolve well at wide-open aperture and throughout the aperture range. Super Multi-Layer Coating reduces flare and ghosting, including in backlit conditions. An included lens hood blocks extraneous light.
A stepping motor and inner focus design provide smooth autofocus during video shooting. The lens works with the Fast Hybrid AF of Sony E-mount cameras and supports face recognition AF, which keeps focus on faces as subjects move. The brass mount has a special seal for dust and splash resistance.
