This filter kit includes ND8, ND16, ND32, ND64, CPL, and UV filters. Constructed with an aluminum alloy frame, silicone, and optical glass, it is robust and durable. The ND filters offer flexible light reduction control (3-6 stops), suitable for various lighting conditions such as seascapes, forest streams, waterfalls, and traffic scenes, helping to achieve long exposure effects. The CPL polarizing filter eliminates reflections and enhances color accuracy and clarity. The waterproof and fog-proof design ensures stable use in humid or low-temperature environments, and it is compatible with official lens caps for easy installation. A double-layer scratch-resistant coating enhances optical performance, providing scratch, oil, and dust resistance, and supporting high-resolution imaging, making it an ideal accessory for outdoor shooting with action cameras.
