This NiSi 150mm Filter Holder is designed to allow for the convenient use of 150mm-wide, 2mm-thick filters on a lens with 95mm front filter threads without vignetting.
The kit includes two main components, a front filter holder and an adapter ring. Use of the filter holder is easily accomplished by first screwing the adapter ring onto a compatible lens. The filter holder's pull-and-release locking pin helps to provide a reliable connection to the adapter ring lens collar while the holder can be rotated 360°, permitting the use of graduated neutral density and other filters that are enhanced by varied positioning.
