The Benro Variable Neutral Density Filter provide filmmakers and photographers a broad range of flexibility in managing their exposure and depth of field. Benro Filters offers an expanded line of round threaded filters for direct mounting to lenses. HD optical technologies are employed in the manufacturing process to ensure our filter surfaces are blemish-free and parallel to one another across the entire optical surface. Quality characteristics of this expanded line of Benro Master Series filters include:
• Schott B270 Glass - Benro Filters Start with the Best Glass on Earth
• WMC (Waterproof Multi-Coatings) - scratch-resistant, waterproof, smudge-proof, and easy to clean.
