Canon EF 50mm Lens - EF 50mm F/1.2L USM

The EF 50mm f/1.2L USM is a professional L series lens designed to replace the EF 50mm f/1.0L USM. It is the shorter of the two f/1.2 lenses Canon makes, the other being the EF 85mm f/1.2L II USM. It is constructed with a metal body and mount, and plastic extremities. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is weather-sealed. A circular, 8-blade diaphragm and maximum aperture of f/1.2 give this lens the ability to create very shallow depth of field effects with smooth background blur. The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The front of the lens does not rotate or extend when focusing.
