Does anyone know if 8-15mm fisheye has filter threads?

Does anyone happen to know if the Canon EF 8-15mm f/4L fisheye even has any threads for a filter despite the elements protruding from the lens body? I was thinking of using step-up and step-down adapters to be able to attach a UV filter without touching the elements. I only have a cropped APS-C sensor (Canon T3i).

No, you cannot use a screw on filter with the 8-15mm. It does have a gel filter in the rear. Also some have used the front mount style gel filters on it as well through mods, but I would note that that is probably not worth the time/effort.
