K&F DJI Osmo Action 4/Osmo Action 5 PRO UV,high-definition lens, anti-reflective green coating on

DJI Osmo Action 4 / 5 Pro — 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.
