• 4 Stop Neutral Density Hard Graduation Filter
• 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 colour 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
• Metallic filter case for storage and transport
