Product Description
This ProMaster 40.5mm Pure Light Filter safeguards your valuable lens from dust, sand, water, oil, and fingerprints—while maintaining exceptional image clarity and natural light transmission.
Crafted from finely polished Schott™ B270 optical glass and coated with advanced hydrophobic and anti-reflective layers, this filter delivers extremely high light transmission, minimal reflectivity, and true-to-life color neutrality. The result is pure, accurate image capture without compromise, plus easy cleaning and reliable lens protection in any environment.
Each Pure Light filter features a matte black coating applied to the glass edge to minimize internal reflections and is precisely mounted in a durable anodized aluminum frame for long-term performance.
For added versatility, Pure Light filters maintain the same front and rear thread size, allowing use with lens caps or stacking with other same-size filters. Every filter also comes in a reusable, eco-friendly snap case that doubles as minimalist packaging and a protective storage solution.
Expertly crafted in Japan, ProMaster Pure Light filters combine premium optics with thoughtful design to deliver professional-grade protection and image purity.
