Features1. A set of filters for Insta360 Ace / Ace Pro, with multi-layer coating, waterproof, scratch-proof, dust-proof and oil-proof, protecting your Ace / Ace Pro lens from all-round damage. Meet the dual needs of ND filter and PL polarized lens, and choose from a variety of filter effects when shooting, including ND/8/16/32 and PL filter. 2. Each filter is made of high-definition optical glass, which has no effect on image quality. After multiple grinding and polishing, it forms a low refractive index to ensure the restoration of the true color of the image to achieve color-accurate photo shooting. 3. The aviation-grade aluminum frame is laser-engraved with a matte black finish to prevent light leakage or ghosting, ensuring that each filter has been rigorously tested; lightweight design, no burden on shooting. 4. The sleeve design is safer and quick to install, and can be tightly fixed on the Ace / Ace Pro during shooting, with zero possibility of loosening. 5. Equipped with a special set of 4 filter boxes, which is convenient for storage and protects the filters. It is easy to carry and replace the filters you want at any time.Package List1.
