B+W 105MM KSM C-POL Round Filter Lens

The B+W 105mm Käsemann Circular Polarizing (KSM C-POL) Filter is a premium optical tool designed to significantly reduce reflections and glare from non-metallic surfaces such as water and glass. Crafted with exceptionally clear Schott optical glass, this filter utilizes a specialized Käsemann polarizing foil that provides superior color neutrality and increased light transmission compared to standard polarizing filters. This makes it an invaluable asset for landscape, outdoor, and architectural photographers looking to deepen blue skies, enhance foliage saturation, and capture crisp, high-contrast imagery without severely compromising their exposure settings.

Beyond its optical prowess, the B+W 105mm KSM C-POL is built to withstand the rigors of demanding professional field work. A standout feature is the edge-sealed glass design, which prevents moisture and humidity from penetrating and degrading the polarizing foil, ensuring long-lasting durability in challenging climates. The optics are housed in a robust, precision-machined brass ring that prevents the filter from jamming or cross-threading on your expensive lenses. Completed with B+W’s signature Multi-Resistant Coating (MRC) to repel water and dirt while minimizing flare, the filter comes securely packaged in a protective case for safe transport and storage.
