The Canon EF 50mm f/1.2L USM Lens is a
peerless super fast standard lens featuring an ultra-large aperture for a
narrow depth of field and soft background blur so loved by photographers
everywhere. The lens is suitable for any shooting situation; its lens
coating and construction are optimized to minimize the ghosting and flare
that frequently occurs when lenses are used with digital cameras. This
high-performance, weather-resistant lens delivers all the superb image
resolution and contrast one can expect in a Canon L Series 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 suppress 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.
