Fast Aperture/Normal Field of View. The 50mm focal length offers a normal field of view that’s useful for just about any type of photography. The f/1.4 aperture provides stellar low-light performance with a shallow depth of field. On APS-C models, the Rokinon 50mm will provide a 75mm equivalent focal length.

Advanced Optics. Don’t be fooled; this is an entirely different optical formula from the 50mm Cine DS T1.5. Three aspherical elements help control distortions and aberrations, all while retaining sharpness and clarity at any aperture or focus distance. The Ultra Multi-Coating controls ghosting and flare for a contrasty, color-neutral image, while the nine-blade aperture makes for some nice bokeh.

Autofocus. A first for Rokinon, the 50mm f/1.4 can use both contrast-detection autofocus and phase-detection autofocus for snappy results.
