K&F Concept Nano-X Magnetic Variable ND Filter ND32–ND512 for DJI Osmo Pocket 4/3

Nano-X Magnetic Variable ND Filter ND32–ND512 for DJI Osmo Pocket 4/3. It is a favourite for filming on bright days, as it lets you keep a cinematic shutter and a wide aperture without blown highlights or swapping filters between takes.

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

Magnetic mount

The filter attaches to the Osmo Pocket lens magnetically, nothing is screwed on and a swap takes a second. The frame is low, so the camera still folds into its rest position with the filter on after power-off — with some other makers’ filters the gimbal does not seat.

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.
