Photographing moving objects, such as waterfalls, requires a natural motion blur for the proper results. This ND2000 Long Exposure Filter from Freewell is designed to add that blur to the DJI Mavic Pro and Pro Platinum drones so you can capture effective long exposure photos of moving objects. The filter features a robust and durable aluminum construction yet is very lightweight to prevent any extra stress on the drone, and it attaches securely by easy snap-on installation. The optics are made of quality glass with eight layers of coating on each side that ensure minimal reflection, minimal glare, and optimal image quality.
