Adjustable ND Filter Fader Nano-X ND8-ND128 67mm K&F Concept

Adjustable Neutral Density Filter

The K&F Concept 67 mm adjustable fader filter is designed for professional photographers and videographers. It provides uniform darkening of the entire image area with an adjustable range from ND8x to ND128x (ND0.9 to ND2.1), corresponding to 3 to 7 stops of exposure reduction.

Advanced Nano-X Coatings

This filter belongs to the Nano-X series, featuring multiple anti-reflective and protective nano-coatings. These coatings reduce unwanted glare, resist water and oil stains, and make fingerprints and other contaminants easy to clean. The filter glass is made of hardened optical glass, offering strong resistance to scratches, chips, and cracks.

Importantly, the filter eliminates the common "X" pattern effect seen in many amateur adjustable ND filters, even at extreme settings, ensuring no color cast or distortion in photos.

Design and Compatibility

The filter has a thin, electroplated aluminum frame with multiple grooves to facilitate smooth operation and prevent jamming on the lens. It is double-threaded and compatible with wide-angle lenses. The bezel includes five control points corresponding to ND8, ND16, ND32, ND64, and ND128, allowing precise and convenient exposure adjustment.

Usage

Adjustable ND filters like this one allow photographers to replace multiple fixed ND filters, reducing the number of accessories needed on set. They enable smooth and quick adjustment of light reduction, ideal for landscape photography, outdoor portraits, and long exposure effects such as flowing water or blurred clouds. The filter also helps achieve shallow depth of field in bright conditions and enables creative night photography with light trails.

The K&F Concept Nano-X series is designed for demanding users seeking high-quality optical performance without color tint or artifacts. Protective coatings enhance image quality and maintain the filter's durability and cleanliness.
