The Haida NanoPro Magnetic Variable ND Filter is designed for the DJI Osmo Pocket 3 and 4, providing adjustable light reduction for video recording and photography in bright outdoor conditions. Its variable neutral density design offers 1 to 5 stops of exposure reduction, helping users manage shutter speed and maintain wider apertures where supported.

Featuring multi-coated optical glass, a durable aluminum rotating ring, and magnetic attachment, this compact camera filter enables convenient exposure adjustments without changing filters. It is suitable for vloggers, travel videographers, and content creators seeking controlled exposure and natural motion blur in daylight scenes.
