the Canon RF-mount Samyang AF 85mm f/1.4 is a short-telephoto lens characterized by its fast f/1.4 maximum aperture. The bright design offers great control over depth of field, for isolating subjects using selective focus, and also excels in low-light conditions. 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.
