## Summary description

## Long description

The Neutral Density (ND) Variable Filter K&F KF01.1835 with a 67mm thread provides adjustable light attenuation from approximately ND3 to ND1000. This variable ND filter is designed to limit incoming light without affecting color balance, enabling longer exposures, wider apertures in bright conditions, and controlled motion blur. The product is suitable for photographers and videographers who require flexible exposure control in changing lighting situations and for creative techniques such as smoothing water, softening clouds, and creating cinematic motion.
Advantages
The K&F variable ND filter delivers continuous density adjustment across a wide range, allowing precise control of exposure without the need to switch between multiple fixed ND filters. Its 67mm screw thread fits lenses with the corresponding filter size and simplifies attachment and removal. The filter is engineered to maintain image sharpness and neutral color rendition while reducing stray light and reflections, supporting both still photography and video capture workflows.
Suitable for
Landscape photography requiring long exposures to smooth water and clouds
Indoor or outdoor videography needing consistent shutter control for cinematic motion
Portraits shot with wide apertures in bright light to achieve shallow depth of field
Architectural and urban scenes where controlled exposure prevents highlights from clipping
Key specifications
Filter type: Variable neutral density (full gray)
Thread size: 67 mm
Density range: approximately ND3 to ND1000 (continuous adjustment)
Primary effect: reduces light intake for longer shutter speeds and wider apertures
Optical properties: designed for neutral color balance and minimal impact on sharpness
How to use
Attach the filter by screwing it onto the front filter thread of a 67mm lens until secure. Rotate the outer ring to adjust the density and observe the viewfinder or live view to reach the desired exposure level. For long-exposure landscape photography, set the composition and focus before applying strong attenuation, then switch to manual focus and exposure lock if needed. When using the filter for video, set the desired shutter speed and aperture first, then fine-tune the filter rotation to maintain consistent exposure throughout the shot.
Usage recommendations
Use a tripod for long-exposure shots to avoid camera shake, and check for vignetting at wide focal lengths if stacking additional filters. Clean the filter surfaces with a microfiber cloth before shooting to prevent spots and flare. For critical color work, verify color neutrality in raw captures and apply white balance adjustments in post-processing if needed.
