The Zen DP-230 230mm (9") Optical Glass Superdome port is the solution for photographers using rectilinear wide angle lenses like the Canon 16-35mm f/2.8 L, Canon 16-35mm f/2.8 L2, Canon 17-40mm f/4 L, Nikon 16-35 f/4 VR, and the Nikon 17-35mm f/2.8.  Make sure to specify your housing type from the drop-down menu above.

Like all Zen Underwater ports, the DP-230 is handcrafted from the finest materials and represents the state-of-the-art design and optical technology.  This yields outstanding optical performance, easily equivalent to or surpassing any other dome currently available at any price. The large radius assures a thin water line for over/under shooting, and the glass surface minimizes water beading.

The interior of the dome element is coated with a magnesium fluoride broadband anti-reflective coating to minimize internal reflections from camera lenses, lettering on cameras, etc., which can be a problem in a bright ambient light situation.

The exterior is treated with a proprietary scratch resistant coating to control lens flare. This coating yields an amazing 99.7%+ transmissive value for true distortion-free images.
