This 114-to-100mm Clamp-On Ring mounts a Bright Tangerine Misfit matte box directly onto a lens with a 100mm front outer diameter, doing away with support rods. Its split design compresses gently to grip the lens, and Z-cuts let it clamp securely so the matte box stays put; the same Z-cuts stop light from behind the lens reflecting off the filters and degrading the image.
