This filter kit is designed specifically for the Insta360 Ace Pro 2 and Ace Pro action cameras, including six practical filters: ND8, ND16, ND32, ND64, UV, and CPL, comprehensively covering everyday shooting and creative photography needs. Whether you're shooting dynamic scenes or pursuing natural colors, this filter kit helps you easily enhance the expressiveness of your images. ND Filter Series: Control Light, Capture the Beauty of Movement ND filters evenly reduce the amount of light entering the lens, allowing you to use slower shutter speeds even in bright environments, easily capturing long exposure effects such as silky flowing water, moving clouds, and car trails. Four stops are available (ND8 to ND64) to meet various scenarios from everyday to extreme lighting conditions. CPL Polarizing Filter: Eliminate Reflections, Restore the Real World CPL polarizing filters effectively eliminate reflected light from non-metallic surfaces, such as water, glass, and plant surfaces, resulting in clearer images and more saturated colors. Particularly suitable for shooting scenes such as blue skies and white clouds, waterscapes, snowfields, and flowers. Superior Optical Structure and Convenient Design Double-sided Multi-layer Coating: Improves light transmittance, reduces ghosting and flare, resulting in clearer images. Quick-release Clip Design: Tool-free, one-press installation, compatible with original lens protection filters. Embedded Silicone Damping Ring: Secure installation, smooth removal. Thickened Optical Glass: 1.5mm thick provides stronger physical protection, eliminating vignetting and ensuring a complete field of view.
