Taken from here: captin nod: The fisheye tin cam (which was found on Gizmodo).
I'm thinking that this may be a quick, fun, one day project after finals are done :rockon:
Fisheye lenses are insanely fun to shoot with. They allow you to shoot at very wide angles - wide enough lenses will get people standing right next to you into the shot. I've always loved the wide angle look in videos, and I thought it'd be an awesome exercise in redundant and needless hackery to build my own.
Here's the gloriously ugly result:
Built using a fisheye peephole as the main lens element and a decapitated soda can as the lens body (!), this attaches directly to my SLR camera. For well under US$20, I ended up with a lens that has nearly a 180-degree field-of-view, adjustable focus, a canon EOS mount, and due to it's stylish and sleek exterior, can generate limitless amounts of admiration ridicule confusion. Unlike commonly (and cheaply) available fisheye adapters, this build does not attach to the front of an existing lens - it's a completely self-contained unit that doesn't require any other optics to work.
