The Canon EF 50mm f/1.2L USM is a normal-length L-series prime also sporting a robust physical design and advanced optical layout. The impressively fast f/1.2 maximum aperture affords a great degree of control over depth of field for isolating subjects and producing desirable selective focus effects. Complementing these qualities is a sophisticated optical composition, which includes one aspherical element to suppress spherical aberrations in order to achieve notable sharpness and clarity. Normal-length prime is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides an 80mm equivalent focal length. One aspherical element helps to suppress spherical aberrations and distortion for a high degree of sharpness and accurate rendering. 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. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
