Haida 43mm Greystone ND 1.8 64x Filter #4778

43mm Greystone ND 1.8 Filter

The Haida 43mm Greystone ND 1.8 filter is a circular neutral density filter designed for lenses with a 43mm thread. It provides a 6-stop exposure reduction using a 64x filter factor and a 1.8 optical density. The filter uses multi-coated optical glass housed in a thin aluminum-alloy ring to maintain clarity and reduce vignetting. Front threads allow stacking with additional filters.

Landscape and long-exposure photographers

This filter suits photographers who need to extend shutter speeds or open apertures in bright conditions for motion blur or shallow depth of field. The multi-coated glass minimizes ghosting and reflections to preserve contrast. Shooters who require variable density control or stronger light reduction beyond 6 stops should look at alternative filter types. Videographers needing smooth exposure transitions may prefer a variable ND solution.

6-stop capacity with 64x factor

The 1.8 density comfortably handles bright daylight scenarios where a 6-stop reduction enables creative motion effects in water or clouds. It runs out when lighting demands more than 6 stops of reduction, such as extremely long exposures during midday sun. The thin ring keeps vignetting minimal on wider lenses, though ultra-wide focal lengths may still show corner darkening when stacked.
