Canon EF 50mm f/1.4 USM Lens

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.

• 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.
• Bright f/1.4 maximum aperture suits working in low-light conditions and also affords great control over depth of field for isolating subjects and using selective focus techniques.
• Gaussian optics design, which includes one aspherical element and two high refractive index elements, notably reduces distortion and spherical aberrations for high sharpness and accurate rendering.
• Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.
• A micro Ultrasonic Motor (USM) is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
• Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
