Use 67mm magnetic filters on SmallRig mobile video cages or a lens backplane with an M-mount with the Attachable M-Mount Filter Adapter from SmallRig. Installation is user friendly and you'll be able to quickly and efficiently install or swap filters with the magnetic mount. A rotating stop helps prevent filters from deviating from their set value or position, while an included magnetic adapter ring enables universal compatibility for attaching 67mm threaded filters.
