4. Canon 48mm drop-in CPL. Fits the non-IS versions of big white guns, e.g, 200 1.8, 300 2.8 non-IS, 400 2.8 non-IS I & II, 500 4.5, 600 4.0 non-IS.
Comes with box. The filter is scratched on one side while the other side is perfect. I really don't know how this come from and honestly this is the second time I've seen the same patern. While it's pretty scary as in the pictures, the scratches are only on the coating of the filter. I have personally seen no affect on the image quality of the lens. [SOLD]
