K&F Concept X-PRO Square ND Filter ND64 100 × 100 mm with Protective Frame

A square ND64 neutral density filter for the K&F Concept X-PRO holder that cuts 6 stops of light without a colour cast. In daylight it stretches the exposure enough for water and clouds to blur into motion. AGC glass with 36 coating layers sits in a protective frame, and a PU leather pouch is included.

Less light, longer exposures

The ND64 filter cuts 6 stops of light and leaves colours unchanged. It suits waterfalls, streams and drifting clouds, where exposures of several seconds are needed even in daylight.

Protective frame

The glass sits in a protective frame by which the filter is handled and slid into the holder, so no fingerprints reach the glass surface. The frame also protects the glass in a fall: dropped from 1.5 m onto flat ground the filter does not break (it cannot protect against a fall onto a sharp edge). The frame design won the iF Design Award and Red Dot 2021.

Glass and coating

The Japanese AGC optical glass is polished on both sides and carries 36 layers of nano coating with 0.15% reflectance. The coating suppresses flare and ghosting, repels water and grease and resists scratches.

For the X-PRO system

The filter is made exclusively for the K&F Concept X-PRO square filter holder; in its frame it does not fit holders of other brands.

Pouch

The filter is stored in a PU leather pouch with a pull tab that slides it out without touching the glass.
