The Ikelite modular port system allows you to build a port out of universal components to accommodate a variety of macro, zoom, and wide-angle lenses. The interchangeable port bodies and extensions combine to create endless combinations for maximum versatility and performance.
Extension length is added to overall lens length accommodated by a given port combination. Lens length is measured as the maximum extended length from attachment point on the camera body. Maximum lens diameter is limited to 8.4cm (3.3").
