The M10-II ND filter is made from aerospace aluminum and provides a equal reduction of light throughout the image. The filter features an anti-color cast NanoPro multicoating that makes for a durable and easy to clean filter. Neutral density filters allow for the use of a reduced shutter speed, and are ideal filters to create long exposure images that capture movement, such as clouds in the sky and the flow of water. The M10-II drop-in filter line is made from aerospace aluminum and feature an easy to use pinch-and-release grip design. M10-II drop-in filters are compatible with both the M10 and M10-II filter holders.
