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.‎
