HOYA Filter 72mm PROND EX 64 Neutral Density 1.8 6-Stop camera filter

72mm PROND EX 64 Neutral Density Filter

This 72mm filter reduces incoming light by six stops with a density of 1.8, giving photographers and filmmakers precise exposure control. It enables slower shutter speeds for motion blur effects or wider apertures for shallow depth of field even in bright daylight conditions. The ACCU-ND technology ensures equal light reduction across visible and infrared spectrums, eliminating unpredictable colour shift. It is built into a lightweight, precision-milled aluminium frame for durability.

Check thread size and filter factor before ordering

Verify that your lens accepts 72mm screw-in filters by checking the front thread diameter printed on the barrel or lens cap. A six-stop reduction requires significant exposure compensation, so confirm your camera can meter or calculate the adjusted settings accurately. Ensure you want a fixed-density filter rather than a variable ND, as this model provides a single, consistent 64× factor. The aluminium frame adds minimal thickness but check for vignetting on ultra-wide lenses.

Upgrades from basic ND filters lacking infrared

Standard neutral density filters often leak infrared light, causing colour casts that worsen with density and long exposures; this filter replaces those with ACCU-ND technology for neutral rendering. It also supersedes lower-density filters when you need a full six-stop reduction for cinematic shutter angles or silky water effects in bright light. The jump is worth it when colour accuracy across varied shooting conditions is critical and you want a single, reliable filter instead of stacking multiple weaker ones.
