Protective UV Nano-X Filter for GoPro Hero 11/10/9 by K&F (model SB7851) - lens protection for action cameras

K&F Protective UV Nano-X Filter (model SB7851) is designed for GoPro Hero 11, Hero 10 and Hero 9 action cameras. This screw-on lens accessory reduces ultraviolet light, helps limit atmospheric haze and maintains image clarity while providing a physical barrier that protects the camera lens from scratches, dust and minor impacts. The compact, low-profile design is compatible with common protective housings and mounting systems used in outdoor, travel and action sports settings.

Advantages

The filter features a multi-coated Nano-X surface that minimizes reflections and preserves color fidelity. Its screw-on mounting ensures stable attachment to compatible GoPro lens threads and keeps the protective element aligned with the camera optics. By combining UV filtration with a durable glass surface, the accessory reduces the need for frequent lens cleaning and lowers the risk of permanent lens damage during active use.

How to use

Clean the optical surface with a microfiber cloth and appropriate lens cleaning solution as needed to maintain image quality.

Usage recommendations

For consistent results, attach the UV Nano-X filter before beginning outdoor recording sessions and inspect for debris before mounting. When using with waterproof or protective housings, confirm the filter does not contact the housing interior to avoid pressure on the lens assembly. Store the filter in a protective pouch when not in use to prevent scratches.
