The NiSi V6 Protection Lens Cap is designed to attach to a NiSi V6 100mm holder’s 82mm adapter ring, when the kit’s filterholder is removed.
While in use, this lens cap can protect a NiSi 86mm Circular Polariser Filter installed on that 82mm adapter ring while the adapter ring remains on a lens.
Perfect to protect the Built-in C-PL and no need to put off the C-PL after use it. Leave it mounted and the cap will protect it from scratches and dust.
