The RF 50 mm 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 54 mm diameter, an extremely bright f/1.2 aperture and can focus as close as 40 cm 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.
