Haida Magnetic Solid ND Circular Polarizer Filter for Haida M15 Filter Holder (6-Stop)

This 6-stop Haida Magnetic Solid ND Circular Polarizer Filter for Haida M15 Filter Holder is designed for use with a separately available Haida M15 Filter Holder. Combining a solid neutral density effect with a circular polarizer effect, this filter's 64x filter factor provides a 6-stop exposure reduction. Its 1.8 optical density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.
