A Prototype of the Canon EF 600mm f/4L IS DO BR USM Lens is showing at the Canon EXPO. Photography Bay had a chance to take several photos of this new lens. Thanks to the diffractive optics inside, the new EF 600mm f/4L DO BR lens is substantially shorter than the current EF 600mm f/4L IS II USM lens (Amazon, B&H).
