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, 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.

Clearly distinguished by its bright maximum aperture, 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. 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.
