The NiSi 86mm adaptor for NiSi 100mm V5/V5 Pro allows the NiSi 100mm V5 holder or NiSi V5 PRO 100mm Aluminium Filter with Enhanced Landscape C-PL to be used with lenses that have a standard filter thread of 86mm. Please note it replaces the main 82mm adaptor which also houses the CPL, so you are unable to use the 86mm adaptor at the same time as the CPL. It features a lightweight, aluminum-alloy construction that has a corrosion-resistant, black anodized finish for durability.
