The 46mm NanoPro MC Clear Filter from Haida is a clear filter designed to provide general lens protection. This optically clear filter does not affect the overall image quality or exposure while helping to prevent dust, scratches, moisture, and other substances from reaching or damaging a lens' front element. To prevent internal ghosting and reflections, each glass surface includes 10 layers of antireflection coatings, which also offer greater protection to the filter and help keep it clean. The Nano coating provides an additional layer that results in an improved beading effect when the surface comes in contact with water or oil, allowing for more efficient cleaning.
This filter is constructed from optical glass for clarity and color fidelity. It features a thin aluminum alloy filter ring that minimizes the potential for vignetting while remaining durable and lightweight.
