Red-Diamond 100mm square ND filter

The Haida Red-Diamond ND is a 100x100mm square filter that fits Haida 100 and 100-PRO holders and other 100mm systems. It provides a fixed 0.9 density, cutting three stops of light for creative exposure control in bright conditions.

Upgrade from resin or uncoated glass filters

Photographers moving from resin gels or older uncoated glass gain hardened 2.0mm optical glass with Nanopro multi-coating that resists shocks, scratches, water and oil. The jump is worth it when filter durability and neutral colour are critical for daily professional use.

Three-stop density for motion blur

The 0.9 factor handles bright daylight when you need slower shutters for smooth water or wider apertures for shallow depth of field. It runs out in extremely high-contrast scenes that demand four stops or more, or when variable density is preferred for changing light.

Questions about this item

What holder size does the 100x100mm Red-Diamond ND filter fit?

It fits the Haida 100 Series, Haida 100-PRO Series, and other standard 100x100mm holders from brands such as Lee, Cokin and Hitech.

How is the filter installed in the holder, and what step is often missed?

Slide the 2.0mm glass plate into the holder's front slot until it seats fully; the step many miss is wiping the Nanopro coating clean first so fingerprints do not get trapped.

Will the multi-coated glass need special cleaning or periodic replacement?

The Nanopro multi-coating resists water, oil and scratches, so normal lens-cloth cleaning is enough and no scheduled replacement is required.
