PGYTECH DJI Mini 3/3 Pro UV Filter can reduce the amount of ultraviolet light that passes into a camera, thus avoids discoloration in photos. Also, as a protective cover, it prevents dust and dirt from coming into contact with the lens. The filter uses professional optical glass and has been ground and polished multiple times for high-definition image. The double-sided, multi-layered coating repels water, oil and is scratch-resistant. It adopts quick release design and will not hinder gimbal calibration.
