The EF 50mm f/1.2L USM is suitable for any shooting situation; its lens coating and construction are optimized to minimize the ghosting and flare that frequently occurs when lenses are used with digital cameras. 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. A Super Spectra coating has also been applied to limit flare and ghosting and promote greater contrast and color accuracy in a variety of lighting conditions. Complementing the imaging attributes, a ring-type USM is employed to deliver quick and quiet autofocus performance along with full-time manual focus control. A ring-type Ultrasonic Motor (USM), along with optimized focusing algorithms and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override. Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
