K&F Concept 77mm Nano-X Variable ND Filter ND8-ND128

K&F Concept 77mm Nano-X Variable Neutral Density (ND) Filter ND8-ND128

This variable ND filter reduces light intake from 3 to 18 stops (ND8 to ND128) without affecting overall color balance, enabling creative control over exposure and depth of field.

Optical Glass and Coatings

• Made from imported AGC German optical glass ensuring no color cast and maintaining image clarity and sharpness.
• Multi-layer nanometer coatings (total of 39 layers) provide waterproof, scratch-resistant, and anti-reflective green coating.
• Both sides feature advanced double-sided multi-layer green coating to reduce reflections from the filter and environment, ensuring HD image quality.

Design Features

• Ultra slim 7.4mm rim design minimizes vignetting on wide-angle lenses (supports focal lengths as wide as 39mm without vignetting).
• Extra tough aviation aluminum frame for durability and prevention of jamming during installation or removal.
• Self-lock frame technology eliminates the common "X" cross pattern seen on variable ND filters, even on wide-angle and telephoto lenses.
• CNC non-slip design for easy handling.

Durability and Protection

• Hydrophobic and scratch-resistant nanotechnology coating repels water, oil, fingerprints, dust, and other contaminants.
• Resistant to extreme weather conditions including wind, saltwater, and abrasive elements.

Compatibility

• Fits all camera lenses with a 77mm filter thread diameter (marked with "ø77mm").
• Recommended lens cap or hood size is 82mm for this filter.

Usage

• Allows use of slower shutter speeds and wider apertures for creative effects such as motion blur and shallow depth of field in bright conditions.
• Ideal for photography and videography requiring variable light reduction without color distortion or image degradation.
