A Legendary Standard Prime for Portraits and Selective Focus
The Canon EF 50mm f/1.2L USM Lens is an ultra-large aperture standard prime designed for Canon EF-mount full-frame cameras, built for photographers who want dramatic control over depth of field and the soft, creamy background blur that has made this lens a favorite for portrait and wedding photography. Its 50mm focal length delivers a natural field of view close to human vision, paired with one of the widest apertures in Canon's L-series lineup.
Designed for Portrait and Low-Light Photography
This lens is made for photographers who want maximum creative control over subject isolation and background separation. Its extremely wide f/1.2 maximum aperture allows for a remarkably narrow depth of field, along with the ability to use faster shutter speeds in low-light situations to reduce motion blur. A rounded 8-blade diaphragm helps maintain smooth, natural-looking bokeh even when the lens is stopped down slightly from its widest setting.
Optical Performance and Build
The optical design includes one large, high-precision aspherical element made from highly refractive glass, engineered to suppress spherical aberrations and maintain the sharpness and clarity expected of Canon's L-series lenses throughout the shooting range. A Super Spectra coating helps control flare and ghosting, promoting greater contrast and color accuracy across a range of lighting conditions. The lens features a robust, weather-resistant construction with dust- and moisture-proof sealing, giving it durability that holds up to demanding professional use.
Fast, Quiet Autofocus with Full-Time Manual Override
A ring-type Ultrasonic Motor (USM), combined with a high-speed CPU and optimized autofocus algorithm, delivers quick, silent, and highly accurate autofocus performance. The lens also supports full-time manual focusing, allowing photographers to fine-tune focus by hand even while in autofocus mode, giving precise control for portrait and studio work where exact focus placement matters most.
