Bel Canon effort

I'm not a big fan of fisheyes, much less a good photographer for such focal lengths, but overall, we must salute the performance Canon Canon 8-15mm fisheye on this because it's not every day that Canon launches in such a goal, this is even if I do mabuse the first time, while Nikon is well versed in this exercise since 1972 with the legendary Nikon AI 6mm f / 2.8 at 220 ° field of view. Yes, you read correctly, the Nikon fisheye can "see" behind you :-)
Filter side: Impossible. Jai noted, however, that he had a screw 77m dug inside the visor. But even if you slipped them a 77mm filter, given that it will not cover the entire field of this fisheye, what good can it be helpful. One explanation: The EW-77 visor must be the same on another Canon telephoto.
