Camera Butter Glass ND Filter for GoPro Hero 8 / Hero 9

This stick-on glass ND filter fits GoPro Hero 8 and Hero 9 action cameras used on FPV rigs, letting you lower shutter speed to follow the 180-degree shutter rule and remove the harsh, jittery look of unfiltered footage in bright sunlight.

Key features

• 1mm hardened optical glass, nano-coated to resist scratches, water, fingerprints and reflections.
• Peel-and-stick backing can be removed, rinsed clean and reapplied repeatedly without losing adhesion.
• Adhesive sits only at the edges of the glass, keeping the optical path completely clear.
• Attaches straight to the lens, so no separate bracket or mount is needed.
• Available in ND4, ND8, ND16 and ND32 strengths to match different lighting conditions.

Choose the strength that matches the light: ND4 for cloudy or overcast conditions, ND8 for some sunlight, ND16 for bright sunlight and ND32 for very bright sunlight, so shutter speed stays low enough to avoid the jittery jello look common on unfiltered action-camera footage.
