Snake River Prototyping V+ Series CP Filter for DJI Phantom 2 Vision Plus Camera V+ Series CP Filter Storage case Microfiber cleaning patch The V+ Series Circular Polarizer Filter combines a lightweight slip-over filter frame for the DJI Phantom 2 Vision+ camera with a professional grade circular polarizer (CP) 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. Filter weight is only 7.2 g, or 0.25 oz! Each V+ 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.
