This is the full-circle (180° view) fish-eye lens, making it all-too-easy to shoot your feet (and even your hands) and producing chromatic aberration at the extreme limit of view.
It is very solidly built (and thus heavy for its size). IQ seems pretty good, but I have not subjected it to minute analysis. Incorporates sky/red/yellow filters.
My only complaint is the screw-on lens cap, which is fiddly and time-consuming to put on/remove - but then it does a great job of protecting the very exposed front element.
Not a lens to use every day - but enjoyable and capable of striking results when you do.
