The DJI Osmo Action 6 ND Filter Set is a simple way to control exposure on bright days, providing steadier shutter performance on snow, sand, or open water. The ND16, ND32, and ND64 filters snap straight over the lens cover, so you can switch strength without removing anything. Each filter uses high-strength glass with stain-resistant coatings, and the set stores neatly in the included case.
