Full frame shooters rejoice! In keeping with the Zen Underwater tradition of excellence we are proud to offer our flagship dome port.
With the DP-230 port you will finally have a port that will do justice to your expensive 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.
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 crystal 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.
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.
For exceptional image quality from a full frame camera the DP-230 is the port you have been waiting for..
