72mm IRND 8 Neutral Density Filter
The HOYA HD MKII IRND 8 is a 72mm neutral density filter designed for photographers and filmmakers who need precise exposure control in bright conditions. It reduces light by three stops while maintaining colour fidelity across visible and infrared spectrums. The slim aluminium frame prevents vignetting on wide-angle lenses and includes front threads for stacking additional filters or caps.
ACCU-ND Infrared Blocking Technology
The defining specification is HOYA's ACCU-ND technology, which equalises attenuation across visible and near-infrared wavelengths to eliminate the colour cast common in long exposures. Improved infrared blocking ensures consistent neutrality during multi-minute exposures for video or stills. Without this spectral balance, footage and images would exhibit unpredictable magenta or green shifts.
Three-Stop Density For Bright-Day Control
At density 0.9 the filter blocks three stops of light, letting users open apertures for shallow depth of field or slow shutters for motion blur in full sun. It handles typical daylight scenarios comfortably, but scenes requiring four stops or more will need a stronger ND or stacked filters. The waterproof top coat eases cleaning between shots.

Questions about this item
How does the 3-stop reduction change exposure in a real shot?
It cuts the light reaching the sensor by a factor of eight, letting you use shutter speeds eight times longer or apertures three stops wider without over-exposing the frame.
What thread standard does the 72mm size follow and what accessories will it accept?
It uses the standard 72mm photographic thread pitch, so any 72mm filter, step-up ring or lens cap will screw on securely.
Will the slim frame clear the hood on a wide-angle lens?
The low-profile aluminium frame is milled to minimise vignetting and includes front threads for stacking or a protective cap.
