Protective UV Nano X Filter for Insta360 Go 3 action camera by K&F (model compatible)

The Protective UV Nano X Filter for Insta360 Go 3 action camera by K&F is a slim, screw-on optical accessory designed to protect the camera lens while maintaining natural color balance and image clarity. Engineered with a UV-cutting glass element and a nano anti-reflective coating, the filter reduces ultraviolet haze and surface reflections without altering exposure or white balance, making it suitable for daylight shooting in outdoor and action environments.

Advantages

The nano-coated surface minimizes reflections and improves light transmission, preserving sharpness and contrast. As a physical barrier, the filter shields the lens from scratches, dust, fingerprints and minor impacts encountered during action sports and travel. The low-profile metal mount ensures secure attachment and minimal vignetting while remaining lightweight for use on compact action cameras.

Suitable for

• Outdoor daytime filming where UV haze may reduce image clarity
• Action sports and travel to protect the camera lens from physical damage
• Everyday use when additional lens protection is desired without color shifts
• Situations requiring reduced surface reflections, such as shooting near water or snow

Key specifications

• Optical type: UV (ultraviolet) cut filter
• Coating: nano anti-reflective coating on both surfaces
• Material: optical glass element with metal low-profile mount
• Function: reduces UV haze, surface reflections and provides physical protection
• Compatibility: designed for use with compact action cameras of the specified model form factor

How to use

Align the filter thread with the camera lens thread and rotate gently until the mount seats securely; avoid cross-threading. Clean both the filter and the camera lens with a microfiber cloth before attachment to prevent trapped particles from scratching the surfaces. When not in use, store the filter in its protective case to avoid dust and impact damage. Remove and clean the filter periodically if moisture or smudges affect image quality.

Usage recommendations

For best results when shooting outdoors, use the UV Nano X filter to reduce atmospheric haze in daylight and to protect the lens during active use. Regular cleaning with a blower and microfiber cloth will maintain optical performance; avoid harsh solvents and excessive pressure on the glass surface.
