Nauticam N120 to N200 Port Adaptor for Cinema Lenses on N120 Cinema and DSLR Housings

The Nauticam N120 to N200 Port Adaptor is a professional cinema system interface designed to expand the capability of N120 LT RED underwater housings by enabling compatibility with the larger N200 cinema port system. This allows cinematographers to use a wider range of high-end cinema lenses underwater without changing their existing housing platform.

Engineered for demanding underwater film production, the adapter integrates advanced mechanical and optical control systems into a compact modular design. It combines precise focus control, iris adjustment, and PL lens handling functionality, making it far more than a simple port converter—it becomes an active control extension of the camera system itself.

A large-diameter precision focus knob with custom-machined gearing ensures smooth, accurate focus pulling with minimal backlash, essential for controlled cinematic underwater work. The integrated PL locking ring system allows lens changes even while the camera remains securely mounted inside the housing, improving workflow efficiency on set.

An optional ergonomic handle can be attached to enhance stability and precision when operating the focus control system.
