• Compatible with Haida 100 or 100-Pro Filter Holder
• 4.5 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required
• Providing a 15-stop exposure reduction, this filter allows you to control depth of field and convey movement more easily
• Filter does not affect coloration of the image and is ideal for use with other filters
• Shock-resistant optical glass construction
• 10 layers of anti-reflective nano coatings on each glass surface prevent internal ghosting and reflections, while further enhancing clarity and color fidelity
• 10 additional scratch-resistant hydrophobic coatings on each glass surface further protect the filter substrate and result in an improved beading effect when in contact with water or oil for greater cleaning efficiency
• Rounded edges for easier placement within a compatible filter holder slot
• When combined with a compatible filter holder, included gasket helps to prevent light from coming in between the filter and the lens behind it, which can have an unwanted effect on exposure
• Metallic filter case for storage and transport
