Aquatech P-135 (example: Sony 24-70mm f4 (Includes a P-50Ex)

This port is made up of a 50mm extension ring (P-50EX) and a front port section to accommodate the zoom range of the lens.  These parts of the port can also be used as an extension ring to combine with Dome Ports, and the front section can be used with other short length prime lenses making it a very versatile combination.

AquaTech Lens Ports feature a threaded system that is interchangeable with all Elite and Delphin model AquaTech Water Housings.  No tools are required to attach or remove the port.  The Element is also replaceable if damaged (repairs will need to be performed by an AquaTech Service center).
