## Long description

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.
Suitable for
 Outdoor photography and videography in bright sunlight
 Action sports such as cycling, surfing, skiing and climbing
 Travel and adventure recording where dust and incidental impacts are likely
 General everyday protection of the GoPro lens during transport and storage

How to use
Align the filter with the camera’s lens thread and rotate clockwise until it seats securely; avoid overtightening to prevent difficulty when removing. Use the filter whenever shooting in bright outdoor conditions to reduce UV-induced haze and when transporting or mounting the camera in environments where dust, sand or minor impacts are possible. 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.
