The Canon EF 50mm f/1.2L USM Lens is a super-fast prime lens featuring an ultra-large aperture perfect for creating cinema-style shallow depth-of-field background blur. A large maximum aperture of f/1.2 provides outstanding speed for shooting in low light conditions with fine control over depth-of-field. The len’s circular aperture helps create an attractive, even background bokeh; ideal for isolating foreground subjects.
A Ring-type USM (Ultrasonic motor) uses ultrasonic frequency vibrations to drive extremely rapid auto focus with near-silent operation. A high-speed CPU and improved AF algorithm contribute further to AF speed. Good holding torque stops the focusing lens group without overshoot, while full-time electronic manual focus override is available without having to switch out of AF.
Canon’s Super Spectra lens coatings and lens element shaping suppress flare and ghosting due to reflection off the image sensor. Coatings also help achieve true color balance and increase contrast for vivid images.
