Neutral Density Variable Filter K&F Adjustable ND3–ND1000, 62 mm

The Neutral Density Variable Filter K&F Adjustable ND3–ND1000, 62 mm is a photographic accessory that provides continuous light attenuation for lenses with a 62 mm filter thread. It allows photographers and videographers to reduce incoming light across a wide range, enabling longer shutter speeds, controlled motion blur and the use of larger apertures in bright environments without overexposure. The filter is suitable for still photography and video work where precise exposure control and creative effects such as silky water, cloud movement or shallow depth of field are required.

Advantages

This variable ND filter offers a broad attenuation range from approximately ND3 to ND1000, giving fine control over exposure without the need to change individual filters. The adjustable design reduces the number of separate neutral density filters you must carry and speeds up workflow on location. Constructed to fit lenses with a 62 mm thread, it maintains optical alignment and allows consistent color rendering when used correctly. The product is compact and lightweight, making it convenient for field work and handheld shooting.

Suitable for

• Landscape photography requiring long exposures for smooth water and cloud streaking
• Cinematic video where controlled exposure and motion blur are needed in bright light
• Portraits or shallow depth-of-field shots in daylight using wider apertures
• Time-lapse sequences that require consistent light reduction

Key specifications

• Filter type: Variable neutral density (adjustable ND)
• Attenuation range: from ND3 to ND1000 (continuous)
• Mount thread size: 62 mm
• Primary function: Adjustable reduction of light entering the lens for longer exposures and aperture control
• Compatibility: Lenses with 62 mm front filter threads

How to use

Thread the filter onto the front of a lens with a 62 mm filter thread and rotate the front element to adjust the density until the desired exposure level or motion effect is achieved. When using the filter for long exposures, secure the camera on a tripod to avoid unwanted camera movement. Check the viewfinder or use live view and a histogram to confirm exposure, and be aware that very high attenuation settings will require longer shutter speeds and potentially higher ISO or wider aperture to maintain proper exposure.

Usage recommendations

When using the adjustable ND filter, set white balance or use a neutral reference to monitor any slight color shifts. Avoid stacking multiple filters if possible to reduce vignetting and preserve image sharpness. For extreme attenuation, verify focus before attaching the filter or use manual focus, as autofocus performance can be affected in very low light caused by high ND settings.
