Canon 50L

The Canon 50mm f/1.2L is a difficult lens to use.  At certain subject-camera distance in a certain aperture range it suffers a focus shift - i.e., the focal plane shifts with aperture.  In some sense the lens is not "reliable" like the 135L or 85L  Nevertheless, the pictures on this page make a good advertisement for the lens.
