NiSi 42255 67mm to 100mm Adapter Ring

The NiSi 42255 is a 67mm-to-100mm system adapter ring that lets photographers mount NiSi 100mm square and rectangular filter holders onto lenses with a 67mm filter thread. It threads onto the lens and connects to the 82mm main adapter ring that ships with NiSi holder systems, bridging the gap between smaller-threaded lenses and the 100mm filter ecosystem. Compatibility spans the V5, V5 Alpha, V5 Pro, V6, V6 Alpha, V6 Switch, V7, V7 Alpha, and C4 Cinema holders, making it a long-term investment that carries forward as you upgrade holders.

Constructed from corrosion-resistant anodized aluminum, the ring is built to withstand regular field use in varied weather conditions. It also functions independently as a 67mm-to-82mm step-up ring, allowing you to attach any 82mm screw-in circular filter to a 67mm lens. For landscape and long-exposure photographers who use multiple lenses with different thread sizes, this adapter is an essential piece of the NiSi 100mm system puzzle.
