Canon 50mm F1.2L USM II - Description:
The Canon 50mm f/1.2l Serious Glass for Serious Photographers The 50mm f1.2 is now the fastest autofocus lens in its class, which makes an essential tool for many professional and advanced amateur photographers.Canon is the only Camera manufacturer to provide professionals and advanced amateurs with Digital SLRs that feature full frame sensors, such as the Canon EOS-1Ds Mark II and EOS 5D digital SLRs. The new complements full-frame cameras, while delivering beautiful results on APS-C/H sized sensor models as well. The 50mm f1.2L lens is a strong testament to Canon's heritage of optical excellence. Every aspect of this exudes professional quality from its wide 72mm filter diameter to its dust and moisture sealed construction. A high refraction glass molded aspherical lens element helps to minimize spherical aberration in Canon 50mm EF USM AF Lens, which is crucial in order to provide fine detail and maximum image quality from corner to corner, even when the is used wide open.

Full frame digital camera users will especially appreciate the benefits of the focal 50mm length, when shooting waist-up portraits while maintaining appropriate subject distance at a wedding time. The large maximum aperture of f1.2 allows to produce shallow depth of field that softens the background and makes subjects "pop" out of a portrait. Photographers can also take advantage of higher shutter speeds to shoot in lowerlight and help prevent blurring caused by subject movement or camera shake. In addition to a large aperture f1.2L, the new also has blazingly fast autofocus speed and response time, thanks in part to Canon's ring-type Ultrasonic Motor (USM), which quietly drives the 50mm f1.2L lens. A full-time manual focus feature in allows photographers to fine-tune the sharpness of their images, even when the lens is set for autofocus. Canon designed the to deliver the best possible optical quality while being tough enough to meet the needs of demanding photographers.

Construction
Eight lens elements in six groups of 50mm f1.2 lens provide high resolution, while advanced coating suppresses flare and ghosting. A glass molded (GMO) aspherical element ensures maximum image quality by reducing spherical aberration and linear distortion.
Dust and moisture resistant components of the Canon 50mm F1.2L lens in it's mount, switches, and focus ring help to protect the lens in a wide variety of shooting conditions.

Passes distance information to E-TTL II
The Canon 50mm lens passes distance information back to the E-TTL II flash system of compatible Canon EOS cameras to ensure optimal flash metering.

Super Spectra coatings
Super Spectra lens coatings and lens element shaping in the Canon 50mm F1.2L lens suppress flare and ghosting - more prone to occur with digital Canon cameras due to reflection off the image sensor. Coatings also help achieve true colour balance and increase contrast for vivid hi-fidelity images.

L-series quality in EF 50mm F1.2L
The EF 50mm f/1.2L USM incorporates Canon's highest standards of precision optics. The L-series is Canon's flagship professional lens range, combining superior image performance and ultimate operability with dust and moisture resistant construction.

Large f/1.2 aperture in Canon 50mm lens
A large maximum aperture of f/1.2 of Canon 50mm f1.2L lens 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 (blurness)
A circular barrel aperture helps to create attractive, even background bokeh; ideal for isolating subjects at large apertures and for compelling portrait photography.

Fast, quiet auto focus
A Ring-type USM (Ultrasonic motor) uses ultrasonic frequency vibrations in the Canon 50mm f1.2L lens 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.
