The Zen Underwater DP-230-IKDL dome port is compatible with all Ikelite Dry Lock housings.  

Like all Zen Underwater ports, the DP-230 is hand crafted from the finest materials and represents the state-of-the-art design and optical technology. Like our highly acclaimed DP-200, it begins with a BK7 glass dome. 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.

For exceptional image quality from a full frame camera, the DP-230 is the port you have been waiting for.
