Mixing a comfortable wide-angle design with an ultra-fast maximum aperture, the Sigma 16mm f/1.4 DC DN C, E Mount is a 24mm-equivalent prime for APS-C-format Sony E-mount mirrorless cameras. Characterised by its bright f/1.4 maximum aperture, this lens is adept at working in low-light conditions, and also affords increased control over depth of field for selective focus control.
