"Perfectly proportioned. The Ikelite housing for the Nikon Coolpix P330 is just-right-sized for carefree travel and a comfortable hold with or without a thick glove. All important camera functions are at your finger tips using a series of heavy duty, custom made mechanical controls. A built-in air cushion is our secret for reduced possibility of fogging due to trapped moisture and superior buoyancy control especially important for shooting steady HD video. Expand your system by adding an AF35 AutoFlash or optional tray with release handle(s), attached with two screws for improved stability underwater and quick break-down during travel. Tray and handles provide superb handling above and below water and act as a jump-off point for your lighting system. Unleash your creativity with wide angle and macro options. An optional wide angle lens allows you to capture more of the scene by increasing your camera's native angle of coverage. The W-30 is specifically designed for digital cameras with 28mm focal length and wider, and provides improved permeability, clarity and brightness over similar external wide angle lenses. There's no need to limit yourself to wide angle for an entire dive, as the W-30 lens can be easily removed and replaced underwater. 67mm threaded close-up lenses also attach directly to the front of the port, no adapter needed. Slight vignetting (shading in the corners) will be present when using an external wide angle lens. Clearly superior"
