SKU CH-KED3-PHWRG

72mm threaded variable ND filter reduces light by 2 to 5 stops with 18-layer multi-coated optical glass and hard-stop design preventing cross-polarization and vignetting from 16mm focal length

  • Superior image clarity from 18-layer multi-coated optical glass
  • Precise 2-5 stop light control with zero cross-polarization risk
  • Hard-stop mechanism prevents vignetting at focal lengths of 16mm and above
  • Durable waterproof, dustproof, scratchproof and oilproof protective coatings
  • Quick 72mm threaded attachment for secure lens fit

Light Control for 72mm Lenses

This 72mm threaded variable ND filter provides 2 to 5 stops of light reduction, equivalent to ND4 through ND32. It suits photographers and filmmakers who need adjustable exposure control on standard daylight shoots without swapping fixed filters.

Optical Performance and Durability

The filter uses Pure High Definition Optical glass with an 18-layer multi-coating to minimise reflections and maximise transmission. A hard stop mechanism prevents cross-polarisation and guarantees zero vignetting at focal lengths of 16mm and wider. Each side carries a protective coating that is waterproof, dustproof, scratchproof and oilproof.

Threaded Attachment and Creative Flexibility

The threaded design secures directly to any 72mm lens thread for quick setup. The variable range lets you control depth of field and motion blur continuously from overcast to bright sunny conditions, replacing a set of fixed ND filters in a single accessory.

Questions about this item

How do I attach the 72mm filter and avoid cross-polarization?

Screw the threaded ring onto your 72mm lens threads until snug; the built-in hard stop prevents rotation past 5 stops, eliminating cross-polarization and vignetting at 16mm and wider.

What upkeep does the 18-layer coated glass need?

The waterproof, dustproof, scratchproof and oilproof coatings on both sides mean only occasional gentle cleaning with a microfibre cloth is required; no re-coating or replacement schedule applies.

At what density does the hard stop engage during long exposures?

The hard stop engages at the 5-stop (ND32) limit, preventing further rotation and density increase even during extended use.
