An especially sleek portrait-length prime, the 56mm f/1.4 DC DN is part of Sigma's
Contemporary series of lenses,
and is designed for use with APS-C-format FUJIFILM X-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. The optical design
utilizes two aspherical elements and one SLD element, which help to reduce both spherical
and chromatic
aberrations for greater sharpness and clarity. 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.
