This Drop-In ND Filter for M10 Filter Holder from Haida provides a 9-stop exposure reduction across the entire image area, allowing a wider aperture or slower shutter speed than normally required to be used. Using a longer shutter speed makes it possible to increase blur to convey a sense of movement, or to dial in a video camera frame rate. Increased density also makes it possible to shoot using wider lens apertures, helping you to shoot with shallow depth of field.

This drop-in filter is made specifically to fit the Haida M10 Filter Holder System. It is constructed from optical glass for clarity and color fidelity, and does not affect the color of the image. To prevent internal ghosting and reflections, each glass surface includes 10-layers of anti-reflection multicoating. The additional nano coating provides an improved beading effect when the surface comes in contact with water or oil, allowing for easier cleaning.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.
