The 56mm f/1.4 DC DN is part of Sigma's Contemporary series of lenses and is designed for use with Nikon Z-mount mirrorless cameras. The lens is characterized by its bright f/1.4 maximum aperture, which suits working in difficult lighting conditions and also offers improved control over depth of field for isolating subjects and working with selective focus techniques. A super multilayer coating has also been applied to suppress flare and ghosting in order to achieve more contrast and color accuracy when working in strong lighting conditions. Complementing the optics is a stepping AF motor, which suits both photo and video applications due to its quick, precise, and near-silent performance. The portrait-length prime is designed for APS-C-format Nikon Z-mount mirrorless cameras and provides an 84mm equivalent focal length. One special low dispersion (SLD) element reduces color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy. A super multilayered 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. The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
