【Compatible with Insta360 Ace Pro 2】 Seamlessly compatible with Insta 360 Ace Pro 2 action camera, these ND (Neutral Density) & Polarizer (Polarizing) lens filter accessories enable you to capture the exciting moments of outdoor activities in different environments. NOTE: Not compatible with an updated version of the Ace Pro 2 featuring a redesigned lens guard, which is a round octagonal shape 【Take Perfectly Exposed Images】 ND8, ND16, and ND32 filters reduce the light by 3, 4, and 5 stops respectively, perfect for long exposure photography in bright sunlight. They allow you to shoot at slower shutter speeds with larger apertures and capture moving subjects with dynamic motion blur effects 【Enhance Saturation & Contrast】 The PL (polarizing) filter minimizes reflection on nonmetallic surfaces, such as glass and water, and improves saturation and contrast for vibrant colors. Note: Always keep the white dot facing up when using the PL filter 【Multicoated HD Optical Glass】 HD optical glass ensures high clarity and accurate color reproduction. Multiple coatings on both sides of the glass are resistant to water, fingerprints, smudge, and scratches, making filters easy to clean (a cleaning cloth included) 【Convenient Snap On Attachment】 Instantly snap onto the action camera and you are ready to go. No need to remove the original lens. Nonslip interiors keep filters firmly in place
