- Wide compatibility: CPL filter designed for GoPro Hero11 Black, Hero11 Black Mini, HERO10 Black, and HERO9 Black. Lens filter kit is crafted from aluminum alloy and optical tempered glass. - Build and durability: 18-layer multi-coated high-definition optical glass. The filter is waterproof and scratch-resistant, with light transmission over 99.5%. Ultra-thin glass frame design prevents vignetting and reduces lens glare. - Performance: CPL filter reduces reflections from non-metallic surfaces such as water and glass, improving clarity and color saturation. Rotating the CPL filter adjusts its effect for varying visual results. - Easy to use: To replace filters quickly, unscrew the existing filter counterclockwise and then rotate the new filter clockwise. - Use scenarios: - Shooting water surfaces (lakes, rivers, oceans) to minimize glare and enhance color. - Urban scenes with glass buildings or windows to reduce reflections. - Outdoor landscapes under bright sun to improve color and contrast.
