Canon EF 50mm f/1.2L
Introduced in December 2006, this lens is a nice performer, capable of beautiful imagery even at f1.2, though corners are slightly soft. At about 15X the price of the 50mm f/1.8, buy it only if you regularly shoot at f1.2 to f/2.8, because its sharpness is inferior to the 50mm f/1.8 at f/4 and slower apertures. In short, it does what it was designed to do: allow very pleasing results at fast apertures—don’t buy it with the expectation of superior performance at f/8!
Unlike the Nikon 58mm f/1.2 NOCT-Nikkor, which has strong curvature of field, the Canon 50mm f/1.2L has little and can safely be used wide open for good sharpness across the field.
Mild hot-spotting beginning at f/4, noticeable at f/8, but manageable for many subjects. The lens hood should be used at all times.
