This RevoRing Magnetic Front & Back Cap Set from H&Y is made to fit the 82-95mm RevoRing Variable Filter Adapter to protect the front and rear filter optics when in use. The caps enable steadfast protection of the VND and CPL glasses, which are an inseparable part of the RevoRing. The front cap attaches magnetically to quickly assure the filter is well protected. Both back and front caps are made of high-quality and lightweight aircraft-grade aluminum.
This cap set is made of lightweight, precision CNC-machined aluminum with a black anodized finish. The lens-facing cap features a soft velvet lining to prevent marring optical surfaces.
