An ideal lens for portraiture, the Sony E-mount AF 85mm f/1.4 from Rokinon is a short telephoto prime distinguished by its bright f/1.4 maximum aperture. This fast design, while benefitting its use in low light, also affords notable control over depth of field for selective focus applications. The optical design features four high refractive index elements, which help to reduce spherical aberrations and distortion in order to realize high sharpness and clarity. One extra-low dispersion element is also featured, which controls color fringing and chromatic aberrations in order to realize a high degree of clarity and color accuracy. Individual elements also feature an Ultra Multi-Coating, which suppresses flare and ghosting for greater contrast in strong lighting. Complementing the optical design is an Ultrasonic Dual Linear motor, and an internal focusing design, which offers fast and quiet autofocus performance. Additionally, a rounded nine-blade diaphragm contributes to pleasing bokeh quality.
