Nauticam N120 Extension Ring 55 II
N120 port system — 55mm extension for the "II" (integrated-bayonet) ports
The Nauticam N120 Extension Ring 55 II adds 55mm of effective length within the current N120 "II" port system — the ports and extension rings built with the integrated bayonet ring introduced in 2022. It stacks with the rest of the Extension Ring II series to set the correct lens-to-port spacing.
This is part of the newer "II" system: it is not interchangeable with the older "with lock" extension rings or detachable-plastic-bayonet ports. Check the compatibility note below before ordering.
Consider this extension ring if you:
- Run the current N120 "II" port system (integrated bayonet ring; ports shipping from 2022)
- Need 55mm to fine-tune lens-to-port spacing
- Are building a stack with other Extension Ring II rings

Compatibility
The Extension Ring 55 II works only with the current "II" port system — ports with the integrated bayonet ring (shipping from 2022) and the Extension Ring II series. It is not compatible with detachable-plastic-bayonet ports, the WACP-1, or the older "with lock" extension rings. Exact port, extension and zoom-gear combinations vary by camera and lens — confirm against the Nauticam N120 port chart for your specific lens before ordering.
