Nauticam N120/N100 0.36x Wide Angle Conversion Port - Deep (WACP-1BD)
The WACP-1BD is the deep-rated version of the WACP-1B, a 0.36x water-contact wide-angle conversion port depth rated to 150 metres. It shares the WACP-1B's ultra-sharp, low-distortion, close-focus wide optics with full zoom-through capability and is designed to work primarily with 28mm-equivalent lenses. It includes an integrated float collar and an interchangeable port mounting ring so it can be fitted to either N120 or N100 housings.
Worth noting: choose this deep version over the standard WACP-1B (85206) if you dive beyond the standard depth rating - it is the 150-metre-rated variant of the same port.
