1. This set of filters is compatible with the MINI 5 PRO and features multi-layer coatings for waterproof, scratch-resistant, dust-resistant, and oil-resistant protection. It provides solutions for neutral density (ND) filters, circular polarizing (CPL) filters, light-blocking filters, and black filter effects. Choose from a variety of filter options including ND16, ND64, CPL, UV, light-blocking, and black filter effects. 2. Each filter is constructed from high-definition optical glass to maintain image quality. Multiple grinding and polishing processes result in low refractive index, ensuring true color reproduction and accurate color capture. 3. The frame is made of plastic with a matte black finish to reduce glare and prevent light leakage or ghosting. Each filter has been tested to ensure it does not add significant weight or interfere with the drone's performance. Each filter weighs only 1.6 grams (refer to product details for net weight). 4. The snap-on design allows for quick and secure installation, keeping the filter firmly attached during flight with no risk of loosening. 5. A dedicated six-slot filter case provides convenient storage and protection, making it easy to carry and change filters as needed.
