N120 Extension Ring 55 II

This N120 extension ring adds 55mm of length to an N120 port system, allowing for precise adjustments to accommodate various lens and camera combinations. It seats cleanly between the housing and port, maintaining the integrity of the N120 mount.

Correct extension length ensures optimal optical performance, especially with wide-angle and macro lenses. An accurately positioned port clears the lens barrel and prevents vignetting, particularly critical when using larger diameter lenses or teleconverters. Use the compatibility finder to determine the required extension for your specific setup.

The ring is constructed to withstand the pressures of underwater environments, ensuring a secure and reliable connection in your N120 Port System. Regular inspection of the O-rings and sealing surfaces is essential for safe operation.
