This is a 30mm N120 extension ring for N120 port systems. It is used to adjust the distance between the camera lens and the port optic, accommodating different lens lengths for proper focus underwater.
Machined from anodised aluminium alloy, the extension ring provides a secure connection between the housing and the port. It features a locking collar for positive engagement, preventing accidental detachment during a dive. This ring is a key component for precise optical setups, especially when working with varied prime or zoom lenses.
Confirm the required extension length for your specific lens and port combination using the compatibility finder before assembly.
