NiSi Protection Lens Cap for NiSi S5 150mm Filter Holder Kits

This NiSi Push-On Lens Cap is designed to attach to a NiSi S5 150mm Filter Holder Kit's adapter ring when the kit's filter holder is removed. While in use, this lens cap can protect a NiSi screw-In filter for NiSi S5 150mm filter holder kits installed on that adapter ring while the adapter ring remains on a lens.
