The 95mm G-COAR 95 Clamp-On Lens Adapter Ring for GPMB Matte Box from Genustech is a split-ring-design, Delrin adapter ring that enables you to mount the Genus Production Matte Box onto a lens with a 95mm front. It clamps onto the outside of the lens and avoids needing to be screwed into the lens' filter threads.
It is advisable to use clip-on matte boxes with lenses that do not have rotating fronts, as rotating fronts may lead to exposure changes when using a polarizer, or vignetting of your image as you matte box rotates.
Made from black Delrin to minimize reflections
The split-ring design makes it easier to mount the adapter on your lens
