K&F Concept Nano-X Variable ND Filter ND32–ND512 for DJI Mini 4 Pro

Nano-X Variable ND Filter ND32–ND512 for DJI Mini 4 Pro, changes the amount of light steplessly as you turn it. It is a favourite for drone video on bright days: it allows a longer shutter so the landscape glides smoothly beneath the drone instead of stuttering, and the strength can be fine-tuned without swapping filters.

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

Light under control with one turn

A variable ND replaces a whole set of fixed grey filters — turning the front ring changes how much light gets through, steplessly. While filming the shutter stays at 1/50 s even as the sun goes behind a cloud and comes back, with no need to stop the take or swap a filter.

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.
