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. Normal 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. Gaussian optics design, which includes two high refractive index elements, notably reduces distortion and spherical aberrations for high 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.

The Canon LP1219 Soft Lens Case is made to carry a Canon EF 100mm f/28, EF 135mm f/2.0L, EF 24-70mm f/2.8, EF 28-70mm f/2.8L, EF 50mm f/1.0L, TS-E 17mm f/4L or EF 85mm 1.2L USM lens. It has a drawstring closure.

The ES-71II Lens Hood from Canon is compatible with the Canon EF 50mm f/1.4 USM Lens and features a black felt interior lining to absorb light and therefore reduce unwanted light reaching the lens. Lens hoods are primarily designed to prevent unwanted stray light from entering the lens by extending and shading the end of the lens.
