The NiSi 95mm adaptor for NiSi 100mm V5/V5 Pro/C4 allows the NiSi 100mm V5 holder, NiSi V5 PRO 100mm Aluminium Filter Holder Australian Edition with Enhanced Landscape C-PL or NiSi Cinema C4 Filter Holder Kit to be used with lenses that have a standard filter thread of 95mm.  Please note it replaces the main 82mm adaptor which also houses the CPL, so you are unable to use the 95mm adaptor at the same time as the CPL.  It features a lightweight, aluminium-alloy construction that has a corrosion-resistant, black anodized finish for durability.
