Description
Product Description
The INON S-MRS Magnet Ring RF14-35 is a dedicated magnetic zoom-control ring designed specifically for the Canon RF14-35mm F4 L IS USM lens. When paired with the compatible INON MRS EXT. Ring 50, it allows the lens’s zoom ring to be operated underwater using INON’s S-MRS (Smart Magnetic Rotary System).
The S-MRS system transfers rotational movement through magnetic attraction between the lens-mounted magnet ring and the control ring inside the compatible extension ring. This optimized magnetic coupling provides smooth zoom operation with reduced play and rattle, giving underwater photographers precise control over the RF14-35mm’s wide-angle focal range.
