Square Neutral-Density Filter

The Haida Red-Diamond ND is a square filter measuring 100 by 100 millimetres and marked with a density of .6, which provides a two-stop reduction in light reaching the sensor. It is intended for photographers who need to lengthen exposure times or open the aperture in bright conditions without shifting colour balance. The filter slides into standard 100-millimetre filter holders from Haida, Lee, Cokin, Hitech and similar systems.

Holder Compatibility and Mounting Limits

The filter fits any holder that accepts a 100-by-100-millimetre square, but it cannot be used with smaller circular-thread systems or with holders designed for narrower widths. Vignetting may appear on ultra-wide lenses when the filter is stacked with additional slots in the holder, so the practical limit is the lens’s front-element diameter and the holder’s slot depth. No adhesive or threaded mount is included; the filter relies solely on the holder’s friction grip.

Light-Reduction Density

The single specification that determines whether this filter suits a given scene is its .6 density value, which equals a two-stop exposure reduction. If a scene requires a stronger or weaker adjustment — such as a six-stop or ten-stop filter — this model will not deliver the needed effect. Photographers who need variable density or a different fixed stop value must choose a filter with another density rating.

Questions about this item

Which density should I choose for a 2-stop reduction?

This model is the 0.6 density, which provides exactly a 2-stop light reduction. Select it when you need to cut two stops; other densities in the range offer different stop values.

What does the 2-stop reduction do in practice?

It darkens the entire image by two stops, letting you use wider apertures or longer shutter speeds in bright conditions without over-exposing the frame.

Will this 100x100mm filter fit my existing holder?

Yes, it is compatible with Haida 100 and 100-PRO holders and also works with standard 100x100mm systems from Lee, Cokin and Hitech.
