Fast Normal-Length Prime. The Rokinon AF 50mm f/1.4 II’s normal field of view is especially well-suited to portraiture, and it’s great for just about anything else you can throw at it. Its fast f/1.4 aperture provides stellar low-light performance with a shallow depth of field. Using an APS-C camera? This lens will give you a 75mm equivalent focal length.

Focus Hold Button and Custom Switch. New to this iteration of the Rokinon 50mm f/1.4 are a focus hold button, which keeps the lens locked at the current focusing distance, and a custom switch, which you can set to allow silent aperture adjustment by rotating the focus ring. The custom switch is compatible with the Rokinon Lens Station.

Advanced Optical Design. This lens’s eight-group/eleven-element design includes three High-Refractive Index elements, one Extra-Low Dispersion element, and two aspherical elements that 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 circular nine-blade aperture produces smooth bokeh for subject-background isolation.

Integrated Autofocus System. The 50mm f/1.4 II’s stepping autofocus motor provides fast, quiet, and precise focus and tracking. It keeps vibration and noise to a minimum, meaning it’s optimized for photo and video applications alike, and it works in conjunction with Sony cameras’ autofocus systems for even greater speed and accuracy. You also get manual-focus override for even greater precision, while the 11.4-inch minimum focusing distance lets you get in close.

High-Quality Build. The 50mm f/1.4 II boasts a durable, weather-sealed, all-metal housing, which means you can use it in inclement weather and unfavorable conditions without worry.
