The WD-4 Wide Angle Conversion Dome provides all of the benefits of a dome port underwater without the limitations.
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. For example, the WD-4 and Canon PowerShot G16 combination provides 28mm angle of coverage with incredibly crisp corners.
The WD-4 Wide Angle Dome is compatible with any Ikelite housing featuring a 3.9-inch diameter lens port. To check compatibility with Ikelite housings, please refer to the housing instruction manual or webpage.
The WD-4 Dome is only effective underwater. It requires water between the back of the WD-4 and the front of the housing's lens port to affect the angle of coverage. Like any wide angle wet lens, it may be used for split shots (half-in, half-out of the water), but there will be two water lines: one in front of the dome and one behind.
The WD-4 Wide Angle Dome is not compatible with external color filters.
