The 16mm f/1.4 DC DN is part of Sigma's Contemporary series of lenses and is designed for use with Canon EF-M-mount mirrorless cameras. The optical design makes use of several low dispersion and aspherical elements, which control color fringing and various aberrations in order to provide high sharpness and clarity throughout the aperture range. Benefitting the optical assets, this lens also sports a stepping AF motor for quick, quiet, and smooth focusing performance that suits both still photography as well as video applications. As part of the Contemporary line within Sigma's Global Vision series, this lens is designed to achieve a balance between convenience and performance and meshes a compact, lightweight build and versatile handling with notable optical attributes. Bright f/1.4 maximum aperture excels in low-light conditions and also affords increased control over the depth of field for achieving selective focus effects. Two aspherical elements are used to limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
