This Haida M10 Enthusiast Filter Kit includes two filters that can be used individually or in various combinations to improve the results of your photography by preventing overexposure, as well as a circular polarizer to prevent distracting reflections or glare. To allow these filters to be placed in front of a lens, this kit contains four filter holder adapter rings as well as a Haida M10 Filter Holder. The filter holder is designed to allow for the convenient use of up to three 100mm wide, 2mm thick filters along with the kit's M10 NanoPro MC Circular Polarizer Filter. A filter case is also included for the storage and transport of the kit. The M10 Enthusiast Filter Kit's drop-in circular polarizer filter is mounted within a geared filter ring assembly with an external dial, which allows for the independent rotation of the circular polarizer filter in order to adjust the intensity of its effect. For still images or video captures where this filter is not in use, a drop-in cover is provided to occupy the filter holder's accessory slot for that filter. The drop-in cover then serves to eliminate stray light from coming in-between any installed filters and the filter holder and the lens behind it. Haida Red Diamond filters are constructed from shock-resistant optical glass. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes 10 layers of anti-reflective nano coatings. An additional 10 scratch-resistant hydrophobic coatings further protect the filter's substrate and result in an improved beading effect when its surfaces come in contact with water or oil, allowing for more efficient cleaning. Additionally, Haida Red Diamond filters feature rounded edges for easier placement within a compatible filter holder slot.
