Designed for the DJI Osmo Pocket 3 and 4, this Haida NanoPro Magnetic 4-Filter Kit offers versatile exposure control and flexibility in a compact size. Suitable for sky-heavy scenes or shots near water and glass, the kit's circular polarizer (CPL) filter minimizes glare and atmospheric haze, improves contrast without affecting color tone, and maintains optical clarity and image sharpness. When working in bright environments, the three included ND filters (ND16, ND64, and ND256) reduce light by four to eight stops to capture crisp, true-to-color, and properly exposed visuals. Each included filter is ultra slim, gimbal safe, and mounts magnetically.
