Fujifilm Quick Snap Waterproof 35mm Disposable Camera (5 Pack) - Single Use Underwater Camera for Beach, Pool & Vacation Photography | Perfect for Snorkeling, Swimming & Outdoor Adventures

I use these cameras all the time! They are great for on-the-go photos at a pool, the ocean, etc. Totally waterproof. They use film and the camera is completely encased in plastic so it's totally submersible. The photos are pretty good quality. You definitely need to make sure you have as much sun light as possible when taking photos underwater. If there is a shadow on the person's face, the photo really doesn't come out well. I suspect this camera would not take great photos in murky seawater. Very good for swimming pool water, since it's clear. The camera takes 27 photos, and you need to either mail it in to the camera maker to develop the photos, or take it in to a shop that will still develop these. Fewer and fewer stores will develop disposables, but you can still find people who will. I recommend this product.
