ND CPL Filter Kit for GoPro Hero13/12/11/10/9 - 4-Pack ND8 ND16 ND32

In this review the 4-pack ND and CPL filter kit is judged on fit, image impact and build for action cameras. It is aimed at GoPro users who want cleaner, more cinematic footage without heavy post processing. The single biggest reason to buy is the combination of three neutral density stops plus a polarizer that fit like factory parts and noticeably reduce reflections and control light for motion blur and richer colors. The kit is compact, uses imported AGC optical glass, and feels like a practical upgrade for outdoor shooting.

Key Features

• Compatible fit: The set is precisely engineered to fit GoPro Hero 13, Hero 12, Hero 11, Hero 10 and Hero 9 Black cameras for a secure, factory-like attachment.
• Imported AGC glass: High grade optical glass keeps footage sharp with no color shift, which helps preserve detail in wide-angle action shots.
• ND stops: ND8, ND16 and ND32 provide 3, 4 and 5 stop light reduction respectively, making it easier to control shutter speed in partly cloudy to bright sun conditions.
• CPL effect: The circular polarizer removes non-metallic reflections from water and glass and deepens color contrast for more cinematic frames.
• Multi-layer coatings: Nanometer coatings make the glass waterproof and scratch-resistant while maintaining high transmittance for clear footage.
• Ultra-thin frame: A slim filter frame reduces the chance of vignetting on the GoPro's wide lens, preserving the field of view.

Who It's For

Outdoor videographers, action-sports shooters and travel creators who use GoPro Hero cameras and want to control exposure and reflections in-camera will get the most from this kit. It is especially useful for anyone who shoots in bright daylight and wants natural motion blur and richer colors without heavy editing.

Less suitable for underwater filming because the hydrophobic coating means the filters are not intended to function submerged, and studio shooters who rarely deal with bright sunlight may not need the ND range provided.

Pros & Cons

Pros

• Good build quality and a secure fit that customers say feels like original equipment.
• Clear image reproduction from imported AGC optical glass with minimal color shift.
• ND and CPL combination offers flexible control over exposure and reflections on a single shoot.
• Protective coatings increase scratch resistance and maintain high light transmittance.

Cons

• The hydrophobic coating means the filters are not suitable for underwater use as a replacement for waterproof housings.
• Ultra-thin frames reduce vignetting but users with extreme wide-angle mounts should still verify compatibility.

Our Verdict

The 4-pack ND and CPL kit is a practical, good-value upgrade for GoPro users who shoot outdoors and want better control over exposure and reflections. With solid build quality, true-to-color imported AGC glass and a useful range of neutral density stops plus a polarizer, it improves cinematic look and motion blur without complicating workflow. It is a worthwhile purchase for action and travel shooters, though not intended as an underwater filter solution.
