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 options for neutral density (ND) filters, polarizing (CPL) filters, light-blocking filters, and black filter effects. Choose from a variety of filter effects, including ND16, ND64, CPL, UV, light-blocking, and black filter effects. 2. Each filter is made of high-definition optical glass to help maintain image quality. Multiple grinding and polishing processes result in low refractive index, helping ensure accurate color reproduction. 3. The frame is made of plastic with a matte black finish to help reduce light leakage and ghosting. Each filter has been tested and is designed to not add significant weight or interfere with device operation. Each filter weighs approximately 1.6 grams (refer to product details for net weight). 4. The snap-on design allows for quick and secure installation, helping ensure the filter remains securely in place during use. 5. A dedicated six-slot filter case provides convenient storage and protection for your filters, making it easy to carry and change filters as needed.
