I have been wanting to purchase a smaller camera, to carry around in my purse and for when we go on vacation, so I don't always have to lug my Rebel around. I really think I'll go for the Canon Powershot SD630. Looking on amazon, I noticed that they also make a waterproof case for this camera. I have never heard of this before! This would be fabulous for snorkeling and around the beach, I'd never have to worry about the camera getting damaged! Has anyone ever bought a waterproof case for a camera? This is actually the first I have ever heard of it, but maybe this has been around for a while? Sounds like a great idea to me, however I would be very hesitant to actually submerge the camera in the waterproof case underwater. How can I be sure it doesn't leak? Just wondering if anyone has ever heard of this/bought this for their camera? If so, what are your experiences?
