An interchangeable lens camera demands a housing with interchangeable lens ports. Some lenses require a zoom or focus gear, please use our Port Selector (at left) to find recommended combinations, or see our Port Charts page for more ideas.
Underwater housings do several things besides the obvious of keeping the water away from your precious camera. They also protect from pressure, allow you to use camera controls, allow for different lens ports and gearing, and also hold other accessories like lighting in a complete system that you can swim with in an underwater environment. It is important to remember that they are only a part of that overall system and you need to take a holistic system approach when shopping for one.
