K&F Concept Action Camera Filters UV, high-definition lens, anti-reflection green film, waterproof

UV filter, protects the front element and filters ultraviolet light.

• 28 anti-reflective layers
• The surface repels water and grease and resists scratches

An MCUV filter does two jobs at once. It filters out the ultraviolet light that puts a bluish veil over distant and mountain shots, and above all it shields the front element — instead of a scratched lens you replace a filter costing a fraction. It has no other effect on the picture, so it can stay on permanently.

The surface repels water and grease, so drops run off and fingerprints wipe away without smears; the coating also stands up to cleaning in the field.

On these cameras the original glass over the lens unscrews and the filter takes its place, so nothing protrudes and the camera still fits a cage or a case.
