In addition to blocking harmful UV light that could damage the camera, the Freewell UV Filter for DJI Mini 4 Pro also acts as a physical barrier against scratches, dirt, dust, and impacts. Additional protection is provided in the form of a filter coating that renders the UV filter dustproof, oilproof, scratch resistant, and color neutral. Using this UV filter, you can pilot the Mini 4 Pro with confidence thanks to Freewell's GimbalSafe technology. GimbalSafe ensures that the filter is lightweight enough to have no harmful effect on the gimbal's operation during flight.
