The NiSi adapter for NiSi M75 75mm Filter System allows the 67mm filter holder adapter ring included with a NiSi M75 75mm Filter Holder Kit to be used on a lens with 40.5mm-62mm front filter threads. It features an aluminum-alloy construction for durability while remaining lightweight.
*Note: The NiSi 72mm adapter for NiSi M75 75mm Filter System allows the M75 holder to support lenses with a filter thread of 72mm. This adaptor replaces the 67mm adaptor that usually holds the CPL, so while using this adaptor you are unable to use the M75 CPL.
