Professional Optical Glass Clear Protective Filter – Precision-Polished Schott B270 Optical Glass, Multi-Coated Hydrophobic & Oleophobic Surface Layers (Resists Dust, Oil, Water, Dirt & Fingerprints), Ultra-High Light Transmission & Color-Neutral Performance, Matte Black Anti-Reflective Glass Edge Coating, Slim-Profile Anodized Aluminum Frame with Double-Threaded Front Ring, Eco-Friendly Hard Storage Snap Case, Crafted in Japan
The ProMaster 105mm Pure Light Protection Filter is a professional-grade optical clear filter engineered to provide transparent, uncompromised front-element defense for high-end telephoto zooms and large-aperture cinema and portrait optics. Crafted with care and precision in Japan, this filter utilizes finely polished Schott B270 optical glass to deliver a color-neutral transmission curve, ensuring that natural color rendition, edge-to-edge resolution, and exposure levels reach the camera’s digital sensor or film plane without degradation.
Engineered to endure harsh outdoor shooting conditions, the filter incorporates advanced hydrophobic and oleophobic multi-coatings that repel water droplets, dirt, oil, and fingerprints, making the surface easy to clean in the field. To virtually eliminate flare, ghosting, and internal barrel reflections, a specialized matte black coating is applied directly to the outer edge of the glass element before precision mounting into its anodized aluminum frame. Featuring a slim profile to minimize vignetting on wide perspectives, the filter retains standard front 105mm threads for attaching original snap-on lens caps or stacking additional filtration tools. It comes complete with ProMaster’s dual-purpose, eco-friendly protective storage snap case.
