## Summary description

Adjustable neutral density (ND) filter from K&F, model KF01.1831 (MPN SB7474), with 52 mm thread. Variable density range ND3 to ND1000 allows gradual light reduction for longer exposures, wider apertures in bright conditions, and motion blur effects. Suitable for landscape, architecture, and long-exposure photography when controlling exposure and depth of field is required.

## Long description

The K&F Adjustable ND3–ND1000 52 mm neutral density filter provides variable light reduction for photography where precise control of exposure and depth of field is required. This circular screw-in filter fits lenses with a 52 mm thread and offers a continuously adjustable density range equivalent to ND3 through ND1000. It is designed to enable longer shutter speeds in bright conditions, allow wider apertures for shallower depth of field, and create motion blur effects for subjects such as flowing water or moving clouds.
Advantages
The adjustable design replaces the need to carry multiple fixed-strength ND filters, allowing smooth transition between light reduction levels. The filter maintains image colour balance and contrast while cutting light, and the 52 mm screw mount ensures secure attachment to compatible lenses. The variable ND range supports both subtle and strong exposure reduction, helping photographers adapt quickly to changing light without swapping filters.
Suitable for
Landscape photography requiring long exposures and controlled highlights
Architecture and urban photography to manage reflections and depth of field
Long-exposure seascapes and waterfalls to create motion blur
Bright-light portraiture when using wide apertures outdoors
Key specifications
Filter type: variable neutral density (adjustable)
Thread size: 52 mm screw-in
Density range: adjustable from ND3 to ND1000 (continuous)
Form factor: circular, slim profile compatible with many lenses
Typical effects: enables longer shutter speeds, wider apertures, and motion blur control
How to use
Screw the filter onto the front of a lens with a matching 52 mm thread until it is snug but not overtightened. Rotate the outer ring to select the desired density, watching the effect through the viewfinder or on the camera monitor. When using strong settings, check for potential vignetting on wide-angle lenses and reduce exposure settings accordingly. Use a tripod for stable long-exposure shots and enable mirror lock-up or electronic front-curtain shutter if available to minimize camera shake.
Usage recommendations
For best results, set white balance after attaching the filter or use a custom white balance to compensate for any subtle colour cast. When working at extreme densities, verify focus and composition before applying the maximum reduction to avoid hunting or exposure errors. Store the filter in a protective case when not in use to prevent scratches and dust.
