The RF 50mm f/1.2L USM from Canon is a desirable normal-length prime due to its versatile focal length and bright f/1.2 maximum aperture. This fast design excels in difficult lighting conditions and also benefits from working with shallow depth of field and selective focus techniques. The optical layout incorporates one UD element and one aspherical element, which help to reduce both chromatic and spherical aberrations in order to produce greater clarity and sharpness. Complementing the imaging capabilities is an apt ring-type Ultrasonic Motor, which delivers fast, near-silent autofocus and full-time manual focus override. Exceptionally bright f/1.2 maximum aperture affords extensive control over depth of field for selective focus applications and also benefits working in low-light situations. An aspherical element is used to correct spherical aberrations and distortion for improved sharpness and accurate rendering. Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
