Its 50mm focal length is ideally suited for portraiture, landscapes, and all-purpose shooting and provides a bright f/1.4 maximum aperture for shallow depth of field control. Based on the latest optical design technology, the lens incorporates 14 elements in 11 groups, with three aspherical lenses and one SLD glass element. The lens effectively suppresses various aberrations such as astigmatism and field curvature, which cannot be corrected in-camera. Additionally, the lens offers fast and quiet focusing and excellent tracking performance allowing the lens to be used in a variety of situations including shooting in dark places, shooting moving subjects, and video.
