SKU CH-1W51-D9764

A 49 mm neutral-density filter that blocks six stops of light with IRND 64 / 1.8 density while preventing colour shift and light leaks

  • Blocks 6 stops of light for long exposures in bright conditions
  • ACCU-ND technology prevents color shift across visible and IR spectrums
  • Improved infrared blocking maintains accurate colors during extended exposures
  • Light-leak proof slim frame eliminates bleeding around filter edges
  • Waterproof top coat simplifies cleaning and protects glass surface

49mm IRND 64 Neutral Density Filter

This 49mm HD MKII IRND 64 filter reduces light by 6 stops using ACCU-ND technology for equal reduction across visible and infrared spectrums. It is designed for photographers and filmmakers who need precise exposure control without colour shift. The neutral density 1.8 rating allows creative depth-of-field and motion-blur effects in bright conditions.

Compatibility Check Before Ordering

Verify that your lens has a 49mm front thread diameter to accept this filter. Ensure the slim profile frame does not interfere with any existing lens hood or cap you intend to use. Confirm that your shooting workflow requires a fixed 6-stop reduction rather than a variable density option. The filter includes front threads for stacking, so check clearance for additional accessories.

Build Quality and Daily Use

A precision-milled aluminium frame provides a light-leak proof seal during long exposures while keeping the profile low. The waterproof top-coat resists moisture and simplifies cleaning in the field. Front filter threads allow you to stack further filters or attach a lens cap without removing the ND filter. The slim construction minimises vignetting risk on wide-angle lenses.

Questions about this item

What comes in the box and do I need a separate adapter for my 49mm lens?

The filter threads directly onto a 49mm lens; no adapter is required and the package contains only the filter itself.

How do I choose between the 64 and 1.8 markings on this filter?

Both numbers describe the same density — 64 is the filter factor and 1.8 is the optical density, each giving a 6-stop reduction.

What does the 6-stop reduction actually do when I shoot video in bright sun?

It lets you keep a cinematic shutter speed and wide aperture instead of stopping down or raising ISO.
