One of the hi-grade coat for anti-reflection.
Its multi layer suppresses excessive
reflection and enables filter to perform
its own function most effectively. |

So called "Non-Reflection Coat", having ultra-low anti-reflection rate. The original plural layers suppresses reflection to the limit. A ultra-superior coat developed by MARUMI. |

An original water repellent coat designed by MARUMI. It repels moisture, makes it turn in water drops in a moment and let them fall down. Quite easy to wipe out glass surface. Recommendable as hi-grade filters without stains and scratches on their glass surface. |

MC - L370 DynamicThe scarcely colored "Dynamic Coat" does hardly affect color reproduction and cut ultraviolet rays. Suitable for shooting with reversal films too. |

|
Water Proof Coat UVUV-Eliminator with an ultra thin frame. The Water Proof Coat-UV is a double coated high performance UV-eliminator. The W ater Proof Coating on the Multi Coating does repel water drops. Its ultra thin frame prevents vignetting at shooting with wide angle lenses.
