K&F Concept Nano-X Pro MCUV filter 82 mm, brass frame

Nano-X Pro — UV filter 82 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.

• 36 anti-reflective layers
• Screws onto a lens with an 82 mm thread.

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 frame is brass, not aluminium. Brass does not seize in the thread, so the filter comes off even after a whole season on the lens. Every piece carries its own stamped serial number and K&F Concept gives a ten-year warranty.
