This is Lomo's underwater camera. Very hard to find. It has a flash, uses 35mm film and is good down to 12 ft - rumored to be "junk" but it is good as a collectors item. Heck I want one... but then again, I am a spider. Do you know how small spider brains are?

As far as I can tell, no one has one to sell. Amazon doesn't have any at the moment, but you can check them with Amazon number: B0006OJ2V8.
