This NiSi Alpha Filter Holder Kit allows for the convenient use of up to two separately available 100mm wide, 2mm thick filters on a Venus Optics Laowa 12mm f/2.8 Zero-D lens without vignetting. This kit comes fully assembled and features an aluminum alloy filter holder that is pre-installed with two pairs of plastic filter slots, a configuration that accommodates two rectangular filters. Each slot is designed to grip an installed filter only along the surface of the filter's edges.
The kit consists of two main components, a front filter holder and a filter holder adapter ring. Use of the filter holder is easily accomplished by first locking the filter holder adapter ring onto the front of a Venus Optics Laowa 12mm f/2.8 Zero-D lens. After being fitted onto the adapter ring, the filter holder's pull-and-release locking pin helps to provide a reliable connection that allows the holder to be rotated 360°, further benefiting the use of graduated neutral density and other filters that are enhanced by varied positioning. To further secure the position of an installed filter, the filter holder also features a screw-in locking pin that prevents any rotation of the filter holder.
