Mixing a comfortable wide-angle design with an ultra-fast maximum aperture, 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. Characterized by its bright f/1.4 maximum aperture, this lens is adept at working in low-light conditions and affords increased control over depth of field for selective focus control. The optical design makes use of several low dispersion and aspherical elements, which control color fringing and various aberrations to provide high sharpness and clarity throughout the aperture range. Individual elements also feature a Super Multi-Layer Coating to suppress flare and ghosting for greater contrast and color fidelity when working in strong lighting conditions. 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.
