SKU CH-BTQH-YEP04

A 100×100 mm neutral density filter reduces light by six stops for long exposures and wide apertures

  • Premium hardened glass delivers exceptional image clarity
  • 6-stop light reduction enables creative long exposures
  • Schott B270 optical glass provides superior scratch resistance
  • 100x100mm format fits standard filter holders
  • Twice the strength of regular glass filters

What the filter does

The Benro Master Hardened Glass 1.8 ND Filter cuts six stops of light, letting you use wide apertures or long shutter speeds in bright conditions. It is built for landscape and long-exposure photographers who need precise density control without colour shift. The 100x100mm square format fits standard filter holders used on many wide-angle and telephoto lenses. It is not for shooters who require variable density or circular screw-in sizes.

Critical specification

The filter provides a fixed 1.8 optical density, equal to a six-stop reduction, which determines exactly how much exposure time you gain. That single number decides whether the filter matches the creative effect you want; no other specification changes the result. Buyers who need a different stop value must choose another density.

Behaviour under sustained use

Schott B270 glass hardened to twice the strength of regular filter glass resists scratches and breakage during repeated field handling. Precise grinding and polishing keep light travelling straight through to the sensor, preserving sharpness even during extended exposures at long focal lengths. The coating maintains consistent transmission without degradation over time.

Questions about this item

What does a 6-stop (1.8 density) ND filter actually do on my lens?

It cuts the light reaching the sensor by six stops, letting you use much longer shutter speeds or wider apertures in bright conditions for motion blur or shallow depth of field.

Will this 100x100mm filter fit my existing holder system?

The 100x100mm square format matches the standard size used by most common filter holders, so it slides into the same slots you already use.

How tough is the Schott B270 glass compared with a regular filter?

The hardened Schott B270 glass withstands twice the peak pressure of conventional glass, giving far better resistance to scratches and breakage in the field.
