Rokinon 21mm f/1.4 Lens for APS Sony E Mount (Pre-Order $499) (Available in Black or Silver) combines a wide-angle perspective with a fast maximum aperture that provides a 31.5mm equivalent focal length. One extra-low dispersion element and a trio of aspherical elements are incorporated into the lens construction, and help to control aberrations and distortions for increased clarity and sharpness. The bright f/1.4 maximum aperture excels in difficult lighting conditions and also enables greater control over focus placement, which is further complemented by the manual focus design and rounded nine-blade diaphragm to produce a quality of bokeh. Additionally, an Ultra Multi-Coating has also been applied to all lens elements to reduce lens flare and ghosting for increased contrast and color fidelity when working in harsh lighting conditions.
