N120 Extension Ring 80 II

The N120 Extension Ring 80 II adds 80mm of length between the camera housing and the port. This extension is for specific wide-angle and zoom lenses where the front element sits further from the camera body. It uses the standard N120 bayonet mount on both ends.

It is made from anodised aluminium alloy for corrosion resistance in saltwater. The locking collar secures the port to the extension and the extension to the Nauticam housing, ensuring a sealed connection. It seats cleanly with an O-ring at each junction.

Compatibility and Setup

Correct extension length is critical for corner sharpness and for clearing the lens barrel inside the port. Refer to the compatibility finder to match this 80mm extension with your specific lens and port combination. Incorrect extension length can cause vignetting or prevent the lens from seating fully.
