Canon Sure Shot WP-1
The Canon WP-1 is a waterproof 35mm film camera.
There is some discrepancy (in Amazon.com reviews) as to whether this camera is actually waterproof or merely weatherproof. I don't know why this is, since Canon's literature states pretty clearly that it's waterproof. I even went a step further and talked to a Canon rep, who confirmed it.
At any rate, I took it swimming with me last weekend, and the inside was bone dry when I opened it up afterward. The picture quality is supposed to be excellent, although I haven't had my film developed yet. At the very least, it should be much better than those one-time-use waterproof cameras you get at the drug store, and you can get one almost as cheaply.
The WP-1 is nearly identical to the Sure Shot A-1, but I don't know what the difference is, other than the color of the grip.
Production of the WP-1 began in April of 1994. Technical specs can be found at Canon's website.
