PGYTECH DJI Mini 3/3 Pro CPLND-PL Filter Set (16 64 128 256) ensures you always shoot with the correct exposure as it limits the amount of light that enters the lens. It also prevents unwanted polarized light. This set can fully satisfy the landscape shooting demands under various conditions. The filter uses professional optical glass as its base material, which 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.
