Canon EF 50mm f/1.4 USM Lens
The EF 50mm f/1.4 USM is Canon’s mid-priced 50mm fast prime, sitting between the inexpensive F1.8 and high-end F1.2 lenses. It offers excellent optical quality, especially when stopped down a bit, and offers a generally more-refined experience than the cheaper lens. It performs very well as both a ‘normal’ lens on full frame cameras, and a short portrait telephoto on APS-C.

Offering a natural perspective along with a fast maximum aperture, 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 and one aspherical element, 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. Complementing the optical design is a micro USM, which enables quick and quiet autofocus performance along with full-time manual focus control.
