ProMaster 40.5mm Protection Filter – Pure Light

ProMaster 40.5mm Pure Light Filter: Ultimate Lens Protection
The ProMaster 40.5mm Pure Light filter is designed to provide ultimate protection for your valuable lens without compromising image quality. This filter is your first line of defense against the elements, including sand, dirt, oil, water, and fingerprints, ensuring your lens stays pristine in any shooting condition.

Uncompromising Image Quality
High-Quality Optical Glass: Crafted from finely polished Schott B270 optical glass, this filter has an extremely high light transmission rating. This means it won’t interfere with the natural light reaching your camera’s sensor, ensuring a pure and accurate transfer of the image.

Hydrophobic Coatings: A special combination of hydrophobic coatings makes the filter incredibly easy to clean. Water, oil, and fingerprints simply bead up and wipe away, so you can spend more time shooting and less time cleaning.

Reduced Reflections: The filter’s glass is treated with a matte black coating on its very edge to minimize internal reflections and prevent flare, ensuring high-contrast images even in challenging light.

Thoughtful Design
Stackable and Versatile: All ProMaster Pure Light filters feature the same size filter thread on both the front and back. This allows you to easily stack them with other filters and use your lens cap without any issues.

Eco-Friendly Case: The filter comes in a compact, eco-friendly snap case that provides minimalist packaging and doubles as a convenient storage case when the filter isn’t in use.

Crafted with care and precision in Japan, the ProMaster Pure Light filter is the perfect blend of protection and performance for your lens.
