67mm NanoPro MC Soft-Edge Graduated Neutral Density 0.9 Filter (3-Stop)

The 67mm NanoPro MC Soft-Edge Graduated Neutral Density 0.9 Filter 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 soft-edged line of transition between the dense and clear areas. A neutral density filter with a soft-edged line of transition is particularly useful for images that do not have a strongly defined transition between the sky and the foreground. The design of this filter incorporates a rotating mount to allow for precise positioning of the gradation along the horizon line. Neutral density filters do not affect the coloration of the image and the density provides up to a 3-stop reduction in light from entering the lens.

This NanoPro MC graduated ND filter is constructed from optical glass for clarity as well as color fidelity. To prevent internal ghosting and reflections, each glass surface includes 10 layers of anti-reflection coatings, which also offer greater protection to the filter substrate and help keep it clean for a longer period of time. The Nano coating associated with the 67mm NanoPro MC Soft-Edge Graduated Neutral Density 0.9 Filter 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.

A thin, aluminum-alloy filter ring assembly minimizes the potential for vignetting while remaining durable and lightweight.
