PGYTECH has combined the four most important neutral density filters in this set: from ND8 to ND64. These ND filters will extend the dynamic range of the Mavic 2 Pro Camera allowing you to capture more professional looking images and video. The filters are made of the very best quality optical glass and aviation aluminium, and therefore are very lightweight.The filters for the DJI Mavic 2 Pro are made of optical glass with multi-coating. They weigh only 1 gram each by applying CNC aviation aluminium for the frame. Thanks to that handy push-on frame, you can simply click them in front of the lens of your DJI Mavic 2 Pro. These filters are a necessary accessory in sunny weather conditions, but also provides excellent protection for the lens.
