Anyone have experience with DroneKinetics filters for their Phantom? Amazon.com: DroneKinetics package of ND2,ND4,ND8,ND16 filters and polarizer for DJI Phantom3: Camera & Photo and Products. I'm a very amateur photographer, just got my first Phantom Advanced a couple weeks ago, and was thinking these might be an inexpensive way to start experimenting with ND filtering. If I order from Amazon, they should be here by the weekend when the weather is supposed to be sunny and beautiful... I've also looked at phantomfilters.com so I'd be open to hear thoughts on those as well. Thanks!
