Compatibility and purpose Designed specifically for the DJI Mini 4 Pro. Combines ND (neutral density) and CPL (circular polarizer) functions to remove reflections, increase color saturation, and boost contrast for clearer, more three-dimensional images. Lowers shutter speed and extends exposure time to prevent overexposure in bright conditions and enable smoother motion capture. Key benefits — why you need it Cleaner, more vivid footage: reduces glare and surface reflections for truer colors and improved contrast. Better exposure control: the ND element lets you slow shutter speeds in bright light for natural motion blur and correct exposure without changing ISO. Reliable in the field: multi-layer nano coating repels water, oil, dirt and resists scratches for longer service life. Features that matter Ultra clear optics: precision-engineered glass, double-sided multi-layer nano coating for water, oil, dirt and scratch resistance. Durable frame: aviation-grade aluminum frame with a laser-engraved logo that won’t fade; black matte finish to prevent light leakage and ghosting. Featherweight: only 0.4 ounces — adds no extra burden to your gimbal and does not affect normal flight of your drone. Practical applications Landscape and scenic shots: reduce atmospheric haze and reflection on water to capture richer colors and deeper contrast at sunrise or midday. Water and coastal footage: eliminate glare off rivers, lakes and the sea for clearer details beneath reflective surfaces. Cinematic video in bright light: extend exposure time for smooth motion blur (e.g., moving clouds, flowing water, or drone gimbal pans) without overexposing highlights. What you get A precision ND+CPL filter optimized for the DJI Mini 4 Pro that improves image quality, protects your lens, and remains light enough for normal drone operation. Technical highlights (concise) Compatibility: DJI Mini 4 Pro only. Coating: double-sided multi-layer nano coating for water, oil, dirt and scratch resistance. Frame: aviation-grade aluminum, laser-engraved logo, black matte finish to prevent light leakage/ghosting. Weight: 0.4 ounces — negligible impact on gimbal and flight performance.
