## Long description

The K&F Neutral Density (ND) Variable Fader Filter for Phone Clip is a compact optical accessory that provides continuous light reduction from ND2 to ND400. Designed to attach to smartphone mounts and clips, this variable ND filter allows photographers and videographers to control exposure and motion blur in bright conditions without changing aperture or ISO. It enables longer shutter speeds for creative effects such as smooth water, motion blur and controlled highlights while preserving color neutrality and image detail.
Advantages
This variable fader filter offers a wide attenuation range in a single, lightweight unit, removing the need to swap multiple fixed ND filters. Its stepless adjustment gives precise control over exposure and motion rendering, making it easier to achieve consistent results when shooting video or long-exposure photos on a phone. The filter is compact and convenient for mobile use, compatible with common phone clip systems and suitable for outdoor shooting in strong sunlight.
Suitable for
 Mobile landscape photography and long-exposure shots
 Smartphone video recording in bright conditions to maintain cinematic shutter speeds
 Reducing highlights and preventing overexposure when shooting handheld or on a gimbal
 Creative motion blur effects such as smoothing water, clouds, or moving subjects
Key specifications
 Type: Variable neutral density (continuous ND) filter
 Density range: Adjustable from ND2 to ND400
 Compatibility: Designed for use with phone clip mounts and smartphone camera setups
 Form factor: Compact, lightweight optical element for mobile use
 Optical performance: Stepless attenuation for fine exposure control and motion blur management
How to use
Attach the filter to the phone clip according to the clip manufacturer's instructions so that it sits centered over the smartphone camera lens. Rotate the outer ring of the fader filter to increase or decrease light reduction until the desired exposure or motion effect is achieved. When composing, monitor the camera app’s exposure readout or histogram, and adjust shutter speed and ISO as required to maintain image quality. Remove the filter when additional light is needed or when night/time-lapse shooting requires maximum sensor sensitivity.
Usage recommendations
For best results, use the ND fader with a stable mount or tripod when targeting long exposures; check for vignetting at wide-angle smartphone lenses after attaching the filter; avoid extreme polarization rotation when combining with other filters. Clean the optical surfaces with a soft microfiber cloth to maintain image clarity.
