Cut the distortion to your wide-angle underwater shots using the WD-3 Wide-Angle Conversion Dome from Ikelite. Featuring a conversion factor of 0.75x, the WD-3 corrects for the refractive magnification of a flat port underwater, resulting in images that are crisp and clear edge-to-edge. Constructed of optical-grade acrylic and weighing less than 6 ounces, this port is substantially lighter than a standard wide-angle wet lens for ease of use. The WD-3 can be slipped on and off of your Ikelite housing's standard port during a dive, so there's no limit to the camera's zoom or macro capabilities. The specific angle of coverage depends on your camera model, however approximately 3/4 of the camera's zoom range can be used with the dome in place. The WD-3 wide-angle dome is compatible with any Ikelite housing featuring a 3.0" diameter lens port.
