Description
Product Description
The INON MRS EXT. Ring 54 is a precision extension ring designed for compatible INON X-2 underwater housinglens and port configurations. As part of INON’s MRS (Magnetic Rotary System), it provides the required extension and supports magnetic operation of compatible lens functions when paired with the appropriate MRS Magnet Ring.
The MRS EXT. Ring 54 is designed to integrate with compatible INON port components, providing proper lens positioning while maintaining a secure underwater connection. Its precision construction makes it ideal for photographers configuring supported lenses that require the 54 mm MRS extension rather than one of INON’s shorter or longer extension rings.

FAQ
What is the MRS EXT. Ring 54 used for?
It provides the required 54 mm extension for compatible INON underwater lens and port configurations while supporting the MRS magnetic lens-control system.
What does MRS mean?
MRS stands for Magnetic Rotary System, INON’s system for transferring rotational control to compatible camera lenses through magnetic attraction.
Does every lens require the MRS EXT. Ring 54?
No. The required extension depends on the exact camera, lens, housing, and port combination. The MRS EXT. Ring 54 should only be used with configurations specified as compatible by INON.
Does the MRS Magnet Ring come with it?
No. This listing includes the MRS EXT. Ring 54 only. The appropriate MRS Magnet Ring, port, housing, camera, and lens are sold separately unless otherwise specified.
Can I use a different MRS extension ring instead?
Only if INON specifies that extension for your particular lens and port combination. Different MRS EXT. Rings provide different spacing and are not automatically interchangeable.
Is this a genuine INON product?
Yes. The MRS EXT. Ring 54 is a genuine INON component designed for compatible X-2 housing and MRS port configurations.
