Red-Diamond 100 x 150 Hard Grad ND0.6 Filter (2-Stop)

This 100 x 150mm Red Diamond Hard-Edge Graduated Neutral Density Filter from Haida is compatible with a M10 and M10 Pro Filter Holder. It helps to darken specific areas of an image, such as bright skies while allowing for a normal, unaffected exposure in the other regions of the image. The filter is densest at the edge and tapers to clear by the middle, with a hard-edged line of transition between the dense and clear areas. A neutral density filter with a hard-edged line of transition is particularly useful for images that feature horizons or any hard transition between the sky and land. Neutral density filters do not affect the coloration of the image and this filter provides a reduction in light from entering a lens.

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 a Red Diamond 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, Red Diamond filters feature rounded edges for easier placement within a compatible filter holder slot.

A metallic case for storage and transport is included, as well as a light-blocking gasket. This gasket forms a seal that is intended to prevent stray light, which could have unwanted effects on exposure, from coming in between the filter and the lens behind it.
