ProMaster 105mm Circular Polarizer Filter (CPL) – Pure Light

ProMaster 105mm Pure Light Circular Polarizing (CPL) Filter
Professional Optical Glass Polarizer – Precision-Polished Schott B270 Optical Glass, High-Efficiency Polarizing Film (Glare Reduction & Sky Saturation), Multi-Coated Hydrophobic & Oleophobic Surface Layers (Resists Dust, Oil, Water, Dirt & Fingerprints), Matte Black Anti-Reflective Glass Edge Coating, Smooth-Rotating Slim Anodized Aluminum Frame with 105mm Front Accessory Threads, Full Autofocus & Metering Compatibility, Eco-Friendly Hard Storage Snap Case, Crafted in Japan

The ProMaster 105mm Pure Light Circular Polarizing (CPL) Filter is a professional-grade optical enhancement tool engineered for large-diameter lenses, telephoto primes, and cinema optics. Essential for landscape photographers, architectural shooters, and cinematographers, a circular polarizer provides optical effects that cannot be replicated in post-production software: cutting harsh surface glare, eliminating reflections from water and glass, deepening blue skies, punching up foliage contrast, and cutting through atmospheric haze.

Crafted in Japan with precision-ground, finely polished Schott B270 optical glass, the Pure Light CPL utilizes premium polarizing films to ensure high light transmission, low surface reflectivity, and color-neutral performance without unnatural color casts. The multi-layer coating includes advanced hydrophobic and oleophobic barriers that resist water droplets, oil, fingerprints, and environmental dirt, making the surface easy to clean in the field. To prevent stray light bounces and internal flaring, a matte black coating is applied directly to the outer perimeter edge of the glass. Encased in a slim, precision-machined anodized aluminum rotating frame, it eliminates vignetting on wide angles while maintaining front 105mm filter threads for standard lens caps and stacked filters. The filter comes housed in ProMaster’s eco-friendly hard protective snap case.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Optical Glare & Reflection Management: Suppresses unwanted reflections on non-metallic surfaces, including water, architectural glass, polished foliage, and glossy paint.

Enhanced Color Saturation & Sky Contrast: Deepens blue skies, makes clouds pop, and enhances natural color saturation without digital artifacting.

Atmospheric Haze Reduction: Cuts through distant environmental haze and humidity for crisper, higher-contrast landscape vistas.

Schott B270 Optical Glass: Manufactured with finely polished German Schott optical glass to preserve resolving power on high-megapixel digital sensors.

Color-Neutral Polarizing Film: Delivers high light transmission while maintaining accurate, uncompromised color fidelity across the entire frame.

Hydrophobic & Oleophobic Coatings: Repels water, grease, dust, and fingerprints for fast maintenance in demanding outdoor conditions.

Matte Black Beveled Edge: Blackened outer glass perimeter suppresses internal barrel flaring and stray internal reflections.

Slim Rotating Aluminum Frame: Low-profile design prevents edge vignetting, and standard 105mm front threading accepts original lens caps and stacked filtration.

Full AF & Metering Compatibility: Designed for digital SLR and mirrorless cameras, ensuring phase-detection autofocus and exposure metering remain accurate.

Japanese Precision Craftsmanship: Engineered and manufactured in Japan to strict optical and mechanical tolerances.
