A redesign of the EF 50mm f/1.2L is under way we're told. The new design will include a floating element like the EF 85 f/1.2L II and get rid of the focus shift problem that many experience with the current version of the lens. The aim is also to make the lens lighter and speed up autofocus performance as well. You could also expect the latest and greatest lens coatings.
We're told this lens will come after Canon's next prime L, which is looking like a 35mm f/1.4 replacement. So we may not see this until very late in 2015 or next year.
