With the widest aperture of any lens in the range, the super-fast Canon EF 50mm f/1.2L USM is a consummate low-light performer: ideal for controlling depth of field and shooting indoors flash free. Its 8 aperture blades produce beautiful background bokeh, whilst its 8 lens elements in 6 groups deliver high-quality optical performance. The Canon ES-78 lens hood is included with the 50mm f1.2L lens. Canon EF 50mm f1.2L USM Lens: Key Features
Large f/1.2 Aperture A large maximum aperture of f/1.2 provides outstanding speed for shooting in low light conditions, without the need for flash. The large aperture also provides fine control over depth of field.
Excellent Background Bokeh A circular aperture helps to create attractive, even background bokeh; ideal for isolating subjects at large apertures and for compelling portrait photography.
Fast, Quiet AF 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. Full time electronic manual focus override is available without having to switch out of AF.
Super Spectra Coatings Super Spectra lens coatings and lens element shaping suppresses flare and ghosting - more prone to occur with digital cameras due to reflection off the image sensor. Coatings also help achieve true colour balance and increase contrast for vivid hi-fidelity images.
Passes Distance Information to E-TTL II The lens passes distance information back to the E-TTL II flash system of compatible EOS cameras to ensure optimal flash metering.
