DP-230 230mm Fisheye Dome Port

Full frame shooters rejoice!

In keeping with the Zen Underwater tradition of excellence, we are proud to offer our flagship dome port. The DP-230 port is the long awaited solution for photographers using rectilinear wide angle lenses like the Canon 16-35mm f/2.8 L II, Canon 16-35mm f/4  L, Canon 17-40mm f/4 L, and the Nikon 16-35 f/4 VR.  For exceptional image quality from a full frame camera, the DP-230 is the port you’ve been waiting for.  The newly designed DP-230-N120-1124D for Nauticam is now compatible with the Canon 11-24mm f/4 and is depth rated to 100m.  Please contact us if you are unsure which model you have.


  • BK7 Optical Glass Dome

    The DP-230 is constructed from hand crafted materials with an optically coated BK7 glass dome at its core. The surface 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.  This coating yields an amazing 99.7%+ transmissive value for true distortion free images.


  • Large Radius

    Assures a thin water line for over/under shooting, and the optically coated glass surface minimizes water beading.

  • Aluminum Shades

    Designed to offer a lifetime of service and extend far enough to protect the dome when placed face down.
