The new WD-4 Wide Angle Conversion Dome provides an elegant and affordable solution for wide angle photography with the Canon PowerShot G10, G11 and Nikon P7000.
The WD-4 simply slides onto the standard port of the Ikelite housing— no modification to or replacement of the housing's original port is necessary. The WD-4 can be removed and replaced underwater so there is no limit to the camera's zoom or macro capabilities. Approximately 3/4 of the camera's zoom range can be used with the dome in place.
The conversion dome corrects for the refractive magnification of the flat port underwater to restore the camera's original angle of coverage.
