【For Action 5 Pro and Action 4 】 Compatible with DJI Osmo Action 5 Pro and Action 4 Adventure Combo, this 4 in 1 set includes 3 filters and a lens for surfing, kayaking, skiing, mountain biking, skydiving, skateboarding, hiking, and other sports. Simply remove the original lens and screw them on for a quick and secure setup. Note: The filters and lens are not weather sealed and not for underwater use, as water will enter and degrade image quality 【Easy & Precise Exposure Control】 The variable ND8-32 neutral density action camera lens filter reduces light by 3-5 stops for flexible exposure control. Rotate the outer frame to marked positions for precise adjustment and creative motion blur. Note: Slight vignetting may appear at the highest ND setting in ultra wide angle mode. This is a normal optical characteristic and does not affect overall image quality 【Minimal Glare & Vibrant Color】 The circular polarizing (polarizer) filter eliminates reflections and glare from glass, water, and other nonmetallic surfaces while enhancing saturation and contrast 【Soft & Dreamy Cinematic Effect】 The black diffusion 1/4 filter smooths out skin texture and adds a dreamy, cinematic effect to your portrait photography, selfies, and personal vlogs 【Wide Angle Lens with 185° FOV】 The wide angle lens expands the field of view (FOV) to 185° and creates a slightly distorted effect for creative shots, perfect for landscape, street photography, and group portraits. Its highly transmissive aspherical lens construction delivers exceptional clarity
