PGYTECH OSMO ACTION Filter ND Set （ND 8 16 32 64) (Professional)

The PGYTECH OSMO ACTION Filter ND Set (ND 8/16/32/64) Professional is a set of four neutral density filters for the DJI Osmo Action camera. Made from German SCHOTT glass using multiple grinding and polishing processes, the filters reduce light by 3, 4, 5, or 6 stops to prevent overexposure and enable motion blur effects with slower shutter speeds. A nanometer-scale, double-sided, multi-layer vacuum coating ensures waterproof, oil-proof, dust-proof, and anti-scratch performance. The aeronautic aluminum frame features a knurling pattern for quick attachment, and the inside is lined with silica gel to protect the original filter from scratches during installation.
