Canon EF 50mm f/1.4 USM Lens

The EF 50mm f/1.4 USM from Canon is a versatile normal-length prime characterized by its bright f/1.4 aperture to suit working in low-light conditions and for producing shallow depth of field imagery. This lens also features a Gaussian optics design, along with two high refractive index elements, to control spherical aberrations and distortion for high sharpness and clarity. A Super Spectra coating has also been applied to suppress flare and ghosting for improved contrast and color accuracy when working in difficult lighting conditions. Standard prime is designed for full-frame Canon EF-mount DSLRs, however, it can also be used with APS-C models where it provides an 80mm equivalent focal length. Gaussian optics design, which includes two high refractive index elements, notably reduces distortion and spherical aberrations for increased sharpness and accurate rendering. A micro Ultrasonic Motor (USM) is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
