Bokeh and Out of Focus Highlights of the EF 50mm f/1.2L and EF 50mm f/1.4

Photographic series were taken at the same camera to subject and subject to background distances with a Canon EOS-1Ds Mark II. Subject and background were each lit with a tungsten modeling light. The focus point was the mannequin's right eye. Images were shot in portrait orientation and full thickness widths were maintained in the cropped image. All images are high quality jpg's out of the camera with the white point set in camera off the grey card.
Summary of results:

• The EF 50mm f/1.2L gives slightly better blurring of background at f/1.4 and f/2.
• Out of focus aperture diaphragm pattern is more rounded with the f/1.2L lens
