Description
Product Description
The INON S-MRS Magnet Ring C8-15 Set is a dedicated magnetic zoom-control accessory set for the Canon EF 8-15mm f/4L Fisheye USM lens. The set combines an S-MRS Magnet Ring with the purpose-built Magnet Ring Adapter C8-15, allowing the lens’s zoom ring to be operated underwater through INON’s S-MRS magnetic control system.
When attached to the Canon EF 8-15mm fisheye, magnetic attraction transfers movement between the lens-mounted ring and the S-MRS Control Ring of a compatible extension ring. INON specifies this set for use with the MRS EXT. Ring 33 or MRS EXT. Ring 111 only; other MRS ports are not compatible. For the Canon EF 8-15mm configuration on the X-2 R5 Mark II, INON pairs it with the MRS EXT. Ring 33, EXT. Ring 18, and M86 Dome Port 110.
