The RF 50mm F1.2 L USM lens delivers a remarkable level of image quality and superlative performance in an elegant design. Engineered expressly for Canon’s EOS R system, it has a large 54mm diameter, an extremely bright f/1.2 aperture and can focus as close as 1.31 ft. /0.40m for excellent operation from almost any distance. Its refined optical formula, engineered specifically for the RF mount, delivers consistent, impressive performance with shallow depth of field and eye-catching background blur. Whether capturing portraits, still life, weddings or anything in between, photographers and videographers can expect gorgeous, detailed and sharp results from the center of the image to the periphery. 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. A rounded 10-blade diaphragm also benefits bokeh quality to suit isolating subjects with depth of field. Complementing the imaging capabilities is an apt ring-type Ultrasonic Motor, which delivers fast, near-silent autofocus and full-time manual focus override. Additionally, a unique Control Ring is integrated into the lens design for intuitive control over exposure settings from the lens itself.
