K&F Concept Nano-X B270 MCUV filter 58 mm

Nano-X — UV filter 58 mm, protects the front element and filters ultraviolet light. 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 %
• Screws onto a lens with a 58 mm thread.
• 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.
