This silver NanoPro MC Clear Filter from Haida has a 1x filter factor and is designed to provide protection for your FUJIFILM X100 series digital camera. This optically clear filter does not affect the overall image quality, but does help prevent dust, scratches, moisture, and other substances from reaching or damaging your camera's front element. To prevent internal ghosting and reflections, it features 10 layers of antireflection coatings, which offer protection to the filter substrate and help keep it clean. A nano-coated layer offers improved beading when the surface comes in contact with water or oil, allowing for more efficient cleaning. The filter is constructed from optical glass for clarity and color fidelity. Its thin, aluminum alloy filter ring minimizes the potential for vignetting while remaining durable and lightweight.
