The WD-3 Wide Angle Dome provides a wider angle of coverage underwater without the distorted edges or vignetting (dark shadows in the corners of the image) that are typically present when using a standard wide angle wet lens.
At less than 6oz (168g), the WD-3 is also substantially lighter weight than the average wet lens and easier to use. The resulting image is crisp and clear edge-to-edge.
The WD-3 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-3 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 (varies by camera model).
The conversion dome features a 0.75x conversion factor to correct for the refractive magnification of a flat port underwater. The WD-3 Wide Angle Dome is compatible with any Ikelite housing featuring a 3.0-inch diameter lens port. To check compatibility with Ikelite housings, please refer to the housing instruction manual or webpage.
The WD-3 Dome is only effective underwater. It requires water between the back of the WD-3 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.
