Abstract: The present invention is directed to a camera lens filter assembly including a camera lens filter and an included optical component. The optical component is installed on an optic mounting part; and a clamp is mounted on a clamp mounting part, so the clamp can press to tighten against the optical component for the purpose of assembly. The present invention efficiently prevents air, dust and other environmental pollutants from reaching the front surface of the camera lens and will also seal to secure the camera lens filter to the camera lens barrel in a way that it will not dismount itself due to vibration, use or other operating conditions.
