The optical construction of this lens contains 8 lens elements, including one ground and polished aspherical lens element. 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. This lens features a wide rubber focusing ring that is damped, a distance window with infrared index, and is fully weather-sealed, when a filter is added to the front. It is constructed with a metal body and mount, and plastic extremities. The EF50mm f/1.2L USM is a professional L series lens designed to replace the EF50mm f/1.0L USM. This, combined with the high production cost and low sales volume, led to it being discontinued in 2000 and eventually superseded by the f/1.2 edition. The front of the lens does not rotate, but does extend when focusing.ĭespite its price and large maximum aperture, the 1.0L was not a particularly sharp lens at any aperture, and the two cheaper 50mm options offered far better sharpness when stopped down beyond about f/2.8. This lens uses a floating front extension focusing system, powered by a ring-type USM motor. The optical construction of this lens contains 11 lens elements, including two ground and polished aspherical lens elements. The 8-blade diaphragm and maximum aperture of f/1.0 give this lens the ability to create extremely shallow depth of field effects and to support low light situations.

In common with the EF 85mm f/1.2L USM it uses an electronic 'focus by wire' system and requires power from the camera in order to manual focus. It also features a wide rubber focus ring that is damped, a distance window with infrared index, and the ability to set the focus range from 0.6m to infinity, or 1m to infinity. This lens has a metal body and mount, and plastic extremities. It was the fastest SLR lens in production during its lifetime. On the used market sells for as much as double the original retail value. The discontinued EF50mm f/1.0L USM is a professional L series autofocus lens.
