Nisi

Nisi 46mm ND-VARIO Pro Nano 5-9 Stops Variable ND Filter

SKU CH-SFF3-CQKRK

A 46 mm variable neutral-density filter with a 5-to-9-stop range and silver density knob for precise exposure control

  • 5 to 9 stops of adjustable exposure control for bright scenes
  • Silver knob enables smooth density transitions while shooting
  • 5 to 2.7 optical density range suits video frame rates
  • 46 mm thread fits compatible lenses directly
  • Pro Nano coating resists reflections and repels water and oil

46 mm variable ND for photo and video

The NiSi 46 mm ND-VARIO Pro Nano filter delivers 5 to 9 stops of neutral density control. It suits photographers and videographers who need precise exposure management in bright conditions. The 1.5 to 2.7 density range supports creative depth-of-field and motion-blur choices.

Optical glass with nano coating

Multi-layer nano coating on every glass surface reduces reflections and protects against water, oil and scratches. The slim frame avoids vignetting on wide-angle lenses while maintaining structural rigidity. No moving mechanical parts contact the optical path during adjustment.

Silver density knob for tactile control

A knurled silver knob lets you rotate the front element smoothly between the marked stop limits. Hard stops at 5 and 9 stops prevent accidental over-rotation and the cross-polarisation artefacts it creates. The filter ships in a protective case for storage and transport.

Questions about this item

How do I fit the 46mm filter onto my lens, and what step is often missed?

Screw the 46mm thread onto the lens front, then rotate the silver knob to vary density; the step often missed is checking for vignetting at the 9-stop end before shooting.

What upkeep will the Pro Nano coating need over time?

Wipe the nano-coated glass with a microfibre cloth and lens solution when fingerprints or dust appear; the coating resists water and oil, so cleaning stays infrequent.

At what density does the variable ND hit its practical limit during long exposures?

The filter reaches its maximum 2.7 optical density (9 stops) at the far end of the knob rotation; beyond that point you cannot increase reduction further.
