When you want versatility underwater a wet lens is the way to go! These lenses are designed to be installed or removed whilst in the water. If you’re diving with your Wide Angle lens on your camera and you see something tiny to photograph, you can simply unscrew the lens from the thread on the front of the housing to remove the lens.

There are many wide angle lenses on the market and we sell this particular one because we have a tried it, and love it!
