K&F Concept Nano-X CPL Polarising Filter for DJI Air 3S

Nano-X — polarising filter, cuts reflections and deepens colour. On drone footage the difference shows straight away: the image looks cleaner and richer, and there is nothing to rescue in post, because glare cannot be removed afterwards.

• 28 anti-reflective layers
• The surface repels water and grease and resists scratches

No glare, deeper colour

A polarising filter takes the glare off water, glass and foliage, and with it brings out the colours that were hiding underneath. The sky darkens, clouds stand out, leaves stop flaring white and you can see through the surface of water. The effect is set by rotating the filter and is strongest at right angles to the sun; it cannot be recreated in post, because it is a property of the light rather than a colour in the file.

The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field. The filter is built for the DJI Air 3S drone: thin enough to close the original gimbal guard over it and light enough not to load the stabiliser.
