K&F Concept Nano-X MCUV UV Filter for Insta360 GO 3 K&F Concept

Podrobný popis

Nano-X MCUV UV Filter for Insta360 GO 3. It is the cheapest insurance for a lens: drops, dust, fingerprints and small knocks land on the filter, while it takes no light and leaves colours unchanged.

• 28 anti-reflective layers, reflectance 0.2 %
• The surface repels water and grease and resists scratches

Protection for the front element

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 glass carries 28 anti-reflective layers and reflects only 0.2 % of the light, so no ghosting or veiling appears against the light. 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. The filter replaces the original lens cover: that comes off with a twist and the filter goes on with the same movement. The slim frame stays out of the picture, so no vignetting appears in the corners even at the wide angle of the GO 3.
