The Canon EF 135mm f/2L USM is a legendary professional telephoto prime lens. Renowned for its superb sharpness, fast autofocus, and beautiful background blur (bokeh), it is widely used for portraits, indoor sports, and events. It is highly prized for its exceptional image quality and relatively lightweight build. I bought this one new and have always used a protective filter on the front + a metal hood (better than Canon's plastic hood). It comes with the metal 72mm hood, 72mm Nikon L1BC filter (Skylight/UV) cased, 72mm Formatt Soft White Mist 2 filter (box), Nikon 77mm Circular Polarizer ($160) with 77-72mm adapter, front & rear Canon caps. It's a great lens, very sharp, super bokeh.
