NiSi 42256 72mm to 100mm Filter Adapter

The NiSi 42256 72mm to 100mm Filter Adapter is a purpose-built accessory that allows photographers to mount NiSi 100mm filter holders—including the V5, V5 Pro, V6, and C4 models—onto lenses with a 72mm filter thread. For landscape and long-exposure photographers who rely on square and rectangular filter systems for graduated NDs, polarizers, and other creative filters, this adapter is an essential link between their glass and their filtration setup.

Machined from aluminum alloy and finished with a black anodized coating, the adapter is built to resist corrosion and wear over time while maintaining a precise thread that seats securely on the lens without play or looseness. Its slim profile helps minimize the risk of vignetting, though photographers using ultra-wide focal lengths should always verify compatibility with their specific lens. As a single-purpose adapter, it does one job and does it well—bridging the gap between a 72mm lens thread and the NiSi 100mm filter system.
