Specialized Canon Lens Abbreviations - Diffractive Optics lenses have special glass elements that bend light more than regular glass. This allows them to be smaller than regular lenses of the same parameters. A well-known Canon DO lens is the telephoto EF 400mm f/4 DO IS USM. It shares the great build quality with the L siblings, but has a green ring around the front rather than a red one.
