Description
Product Description
The INON MRS EXT. Ring 33 is a precision extension ring designed for compatible INON X-2 underwater housing lens configurations using the M96 port system. Installed between the housing and compatible lens port, it adds the necessary extension to correctly position supported lenses inside the port while maintaining the secure connection required for underwater photography.
As part of INON’s MRS (Magnetic Rotary System), the MRS EXT. Ring 33 also supports compatible magnetic lens-control configurations, allowing supported zoom or focus functions to be operated without a conventional mechanical gear connection. Its corrosion-resistant construction and precise M96 threaded interface make it a dependable component for building compatible INON lens and port combinations.
