Description
Product Description
The INON S-MRS Focus Ring RF15-30 is a dedicated magnetic lens-control accessory designed specifically for the Canon RF15-30mm F4.5-6.3 IS STM lens. Used with the compatible INON MRS EXT. Ring 54, it allows the lens’s focus/control ring to be operated underwater through INON’s S-MRS magnetic control system.
The S-MRS system transfers rotational movement through magnetic attraction, providing smooth lens operation without a conventional mechanical gear connection. For photographers using the versatile RF15-30mm underwater, the S-MRS Focus Ring RF15-30 provides access to compatible focus/control-ring functions while the camera and lens remain safely enclosed inside the housing.

FAQ
What does the S-MRS Focus Ring RF15-30 control?
It provides underwater operation of the focus/control ring on the Canon RF15-30mm F4.5-6.3 IS STM through a compatible INON S-MRS housing configuration.
Which extension ring does it work with?
It is designed for compatible configurations using the INON MRS EXT. Ring 54.
Does this control the lens zoom?
No. This is the Focus Ring RF15-30. Zoom operation requires the separate S-MRS Zoom Ring RF15-30.
Can the lens control ring be assigned to other camera functions?
The Canon RF15-30mm’s focus/control ring can support different functions depending on camera and lens settings. Available underwater control therefore depends on how the camera is configured.
Does this include the MRS EXT. Ring 54?
No. This listing includes the S-MRS Focus Ring RF15-30 only. The extension ring, zoom ring, port, housing, camera, and lens are sold separately.
Can I use this with other Canon RF lenses?
No. This version is specifically designed for the Canon RF15-30mm F4.5-6.3 IS STM.
