I'm working with the wording as written. Theorize about something Canon would obviously never do all you want.Fixed aperture is not the same as fixed maximum aperture. As to whether Dantana is right about the OP being a typo, only the OP'er can say. But the discussion is about consumer lenses and a mirror lens fits both the OP and the thread, which is a hell of a lot better than most of the posts here.
