his NiSi Filter Holder Kit allows for the convenient use of up to two separately available 100mm-wide, 2mm-thick filters, along with an included circular polarizer 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 bayonet 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 lever 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.
Together, the adapter ring and filter holder also accommodate the included NiSi 86mm circular polarizer filter while allowing that filter’s edges to be easily gripped for convenient installation or removal. When combined with the filter holder and the adapter ring, the polarizer filter can be rotated to adjust its effect. In such instances, an external dial on the adapter ring allows for the independent rotation of the circular polarizer.
