The P3 & P4 Series filters from Snake River Prototyping are professional slip-over filters for the DJI Phantom 3 and DJI Phantom 4. The filter combines a lightweight slip-over filter frame for both the DJI Phantom 3 and DJI Phantom 4 cameras with a professional grade two-in-one filter. The ND/CP line combines a circular polarizer and neutral density filter. A CP filter is used to reduce glare on the surface of water or windows, manage reflections, and increase the contrast between clouds and sky. A neutral density filter is used to reduce the effects of rolling shutter including the jello effect and prop blur. Filter weight is only 7.5 g!
Each P3 & P4 Series Filter is made from two CNC machined Delrin® pieces so that the filter frame can be disassembled to facilitate easy cleaning of the filter glass. Delrin, which is more costly than billet aluminum by volume, was selected because of its high quality and excellent machining qualities. The Phantom 3 and Phantom 4 camera lens bodies can vary slightly from camera to camera. To insure a secure fit, each P3 & P4 Series filter includes an o-ring on the inside diameter of the filter which will accommodate small variations in camera lens diameter.
