Overview

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.

Pros & Cons

👍 Pros

  • Precision-machined aluminum alloy construction provides a snug, wobble-free fit on 72mm lens threads.
  • Black anodized finish resists corrosion and reduces the chance of unwanted reflections.
  • Compatible across multiple NiSi 100mm holder generations including V5, V5 Pro, V6, and C4.
  • Lightweight design adds virtually no bulk to the lens and filter setup.

👎 Cons

  • Only fits 72mm lens threads, so lenses with different filter sizes require separate adapters.
  • Does not include the filter holder itself, which must be purchased separately.
  • Step-up or step-down rings are not included for adapting other thread sizes to 72mm.

Frequently Asked Questions

This adapter works with the NiSi 100mm V5, V5 Pro, V6, and C4 filter holder systems.
It is constructed from aluminum alloy with a corrosion-resistant black anodized finish, ensuring durability and a secure fit without adding significant weight.
Vignetting depends on the specific lens and filter holder combination. On most 72mm threaded lenses the adapter sits close enough to avoid vignetting, but ultra-wide-angle lenses should be tested to confirm.
The adapter is designed to integrate directly into the NiSi 100mm filter holder system, so it works alongside the holder's standard filter slots and any compatible accessories like landscape polarizers.
