The EF 50mm f/1.2L USM Lens from Canon is
a fast prime lens featuring a particularly large maximum aperture
for effective low-light and shallow depth of field capability. As a
standard focal length lens, it is suitable for most any shooting
situation and its lens coating and optical construction are optimized to
minimize chromatic aberrations, ghosting and flare. A truly circular diaphragm
results in pleasing out-of-focus areas.
An ultrasonic autofocus motor (USM) provides fast, smooth
and quiet autofocus action and manual focus override allows for precise manual
focusing even in AF mode. With a tight seal structure and the addition of the
optional Canon protect filter, the 50mm f/1.2L lens is moisture and dust proof.
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 background
bokeh; ideal for isolating subjects at large apertures and for compelling
portrait photography.
Fast, Quiet Autofocus
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 color 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.
