Screw-in UV filter blocks light to 395 nm and replaces the circular polariser in the S5 150 mm holder system

  • Blocks UV light up to 395 nm for clearer images
  • Replaces native circular polariser in S5 150 mm holder system
  • Optical glass with multi-coating reduces glare and improves quality
  • Raised front edges enable quick installation and removal

Dedicated UV Blocking Filter for S5 Holder

The NiSi Pro Screw-In UV Blocking Round Filter replaces the native circular polariser in the S5 150mm filter holder system. It blocks ultraviolet light up to 395nm to prevent flare and preserve image quality. The filter uses high-quality optical glass in a precision-machined aluminium frame for durability and optical clarity.

Landscape shooters using the S5 system

Photographers who rely on the S5 holder and want a dedicated UV blocker instead of a polariser will find this filter a direct fit. It stores in the S5 case front compartment or its own nylon sleeve for quick access. Shooters who do not own the S5 holder or who need a front-thread circular filter for direct lens mounting should look elsewhere.

Consistent UV rejection during long sessions

The optical glass and multi-coated construction maintain transmission and flare control during extended outdoor use. The aluminium frame resists heat buildup and handling stress without warping or loosening in the holder. Raised front edges allow fast swaps even with cold or damp fingers, keeping workflow steady over hours of shooting.

Questions about this item

Which NiSi filter holder must I already own for this UV blocking filter to fit?

This filter is designed to replace the native circular polarizer in the NiSi S5 150mm filter holder system, so you need that holder for it to work.

Will using this filter prevent me from keeping my existing circular polariser in the S5 holder?

Yes, this UV blocking filter replaces the native circular polarizer in the S5 holder, so you cannot use both at the same time.

How can I confirm the filter is correctly installed and blocking UV light up to 395nm?

The raised front edges allow easy installation and removal; once seated flush in the S5 holder it is working as intended.
