Overview

The NiSi 77958 86mm Adapter is designed for photographers and cinematographers who need to pair their NiSi 100mm filter system with lenses that have an 86mm front filter thread. Rather than stacking step-up rings or hunting for third-party workarounds, this adapter threads directly onto the lens and accepts NiSi's V5, V5 Alpha, V5 Pro, V6, V6 Alpha, V6 Switch, V7, V7 Alpha, and C4 Cinema holders, providing a solid, purpose-built connection point.

Machined from aluminum alloy and finished with a black anodized coating, the adapter is both lightweight and resistant to corrosion from moisture and salt air—an important consideration for landscape shooters working near water. The one trade-off to be aware of is that this 86mm ring replaces the standard 82mm adapter that ships with most NiSi holders, which means the integrated circular polarizer slot is no longer accessible. If CPL use is critical to your workflow, you will need to plan an alternative polarizing strategy. For everyone else, this adapter is a clean, reliable way to bring NiSi's filter ecosystem to larger-threaded glass.

Pros & Cons

👍 Pros

  • Enables NiSi 100mm filter holders to fit the less common 86mm lens thread size without step-up ring workarounds
  • Corrosion-resistant anodized aluminum construction is lightweight yet durable
  • Broad compatibility across NiSi V5 through V7 holder generations and the C4 Cinema holder
  • Precision-machined for a secure, wobble-free connection between lens and holder
  • Simple thread-on installation with no tools required

👎 Cons

  • Replaces the 82mm main adapter, so you lose the ability to mount the circular polarizer on CPL-equipped systems
  • Only useful for lenses with an 86mm filter thread, which limits its audience to a small number of large-diameter lenses
  • Does not include the filter holder itself—sold separately
  • No carrying pouch or case included for protection during transport

Frequently Asked Questions

It is compatible with the NiSi V5, V5 Alpha, V5 Pro, V6, V6 Alpha, V6 Switch, V7, V7 Alpha, and the C4 Cinema filter holder for 4" x 4" cinema filters.
No. Because the 86mm adapter replaces the standard 82mm adapter ring, the CPL attachment point is no longer available on holder models that support one.
It is machined from aluminum alloy with a black anodized finish for corrosion resistance and durability.
Yes, the adapter is lens-brand agnostic—it threads onto any lens with a standard 86mm front filter thread.
No, it threads directly onto your 86mm lens and the V6 holder clamps onto the adapter just as it would onto the standard 82mm ring.
