Because digital cameras come in many shapes and sizes, underwater housings are specific to individual cameras. If you don’t get a housing made for your camera, you may not be able to access all of its controls.
Some digital camera companies sell underwater housings for their products. At the bottom of this story, you’ll find a list of housings and compatible cameras from Canon, Olympus, and Sony.
You can also buy underwater housing from companies that specialize in underwater photography. Again, these cases are usually tailored to specific manufacturers and models. Check the well-known Acquatica, Ikelite Underwater Systems, Light and Motion, and Sea & Sea.
When Budgets Matter
While the companies above have sterling reputations, you may be put off by the prices. If you’re a casual snorkeler who merely wants to keep your camera dry without spending close to the original cost of your camera, consider “flexible housing” (essentialy, plastic bags with glass lenses) from EWA-marine.
