Ikelite WD-4 Wide-Angle Conversion Dome Port

Cut the distortion to your wide-angle underwater shots using the WD-4 Wide-Angle Conversion Dome from Ikelite. Featuring a conversion factor of 0.75x, the WD-4 corrects for the refractive magnification of a flat port underwater to restore the camera's original angle of coverage, resulting in images that are crisp and clear edge-to-edge. This port is constructed of an optical-grade acrylic dome and a flat piece of optical-grade glass. The WD-4 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. For example, the WD-4 and Canon G10 combination provides a 28mm angle of coverage with incredibly crisp corners underwater. The WD-4 wide-angle dome is compatible with any Ikelite housing featuring a 3.9" diameter lens port.
