• The filters are perfect for DJI Action 4, multi-layer coating, waterproof, anti-scratch, anti-dust, and anti-oil, and protect your equipment lens from all-around damage.

• Each filter is made of high-definition optical glass, which has no effect on image quality and has been ground and polished many times to form a low refractive index, ensuring the true color reproduction of the image for color-accurate photo shooting
• The aircraft-grade aluminum frame is laser-engraved with a matte black finish that prevents light leakage or ghosting and ensures that each filter is rigorously tested; lightweight design for burden-free shooting
• The knob design for safer and quicker mounting can be tightly fixed on the Action 4 during shooting, with zero possibility of loosening
• Equipped with a special filter case, easy to store and protect the filters, no burden to carry, change the filters you want at any time
