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.  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. Very bright f/1.4 maximum aperture benefits working in low-light conditions and offers great control over depth of field for isolating subjects and working with selective focus.
