## Summary description

Variable neutral density (ND) filter by K&F Concept in 77 mm size, model Fader with adjustable density range ND2 to ND2000.

Designed for landscape, long-exposure and videography; fits lenses with 77 mm filter thread.

## Long description

The K&F Concept 77mm Fader Neutral Density Variable Camera Filter (ND2–ND2000) is a gray adjustable filter designed to reduce incoming light uniformly across the image plane. With a 77 mm thread size, this variable ND filter covers a wide density range from ND2 to ND2000, enabling longer shutter speeds, wider apertures in bright conditions, and controlled motion blur for stills and video. The optical surfaces receive a Nano-C coating to help reduce reflections and maintain image contrast while minimizing ghosting.
Advantages
This variable neutral density filter offers a continuous range of light reduction without the need to carry multiple fixed ND filters, simplifying exposure control in changing lighting conditions. The gray optical element provides neutral color balance and the Nano-C coating improves resistance to flare and reflections. The 77 mm metal-threaded mount ensures secure attachment to compatible lenses and straightforward stacking with other threaded accessories when required.
Suitable for
 Landscape photography requiring long exposures to smooth water and cloud movement
 Long-exposure urban and architectural photography to remove people or create motion effects
 Videography for controlling shutter speed and achieving cinematic motion blur in bright light
 Portrait or product work when using wide apertures outdoors in strong sunlight
Key specifications
 Filter type: Variable neutral density (gray)
 Density range: ND2 to ND2000 (continuous adjustment)
 Thread size: 77 mm
 Coating: Nano-C anti-reflective coating
 Mount: Metal threaded frame compatible with 77 mm lens threads
 Primary benefits: Light reduction for longer exposures, aperture control, and motion blur management
How to use
Screw the filter onto a lens with a 77 mm filter thread until it is seated securely but not overtightened. Rotate the front ring to adjust the density between ND2 and ND2000 while monitoring exposure through the viewfinder or on the camera display. When composing, set the desired shutter speed and aperture, then fine-tune the filter rotation to reach the target exposure or creative effect. If stacking other filters, check for vignetting at wide focal lengths and remove unnecessary elements to avoid image degradation.
Usage recommendations
To reduce the risk of cross-polarization and X-pattern artifacts at extreme settings, avoid using the filter at its absolute maximum density if precise uniformity is required; rotate slowly while observing the image. Use a tripod for long exposures, and consider metering without the filter first or using live-view exposure preview to achieve accurate results. Clean the coated surfaces with a microfiber cloth and lens cleaner to maintain optical performance.
