B+W Käsemann Circular Polarising Filter (46 mm, High Transmission, MRC, F-Pro, 16x Hardened, Professional)

• Reflex reduction par excellence – reduces reflections to e.g. water, windows or paint and increases colour saturation and contrast and ensures superior sharpness. High light transmission yet excellent efficiency
• ATTENTION: The 7+1 MRC coating ensures high transmission and maximum anti-reflection. The outer layer is dirt and water resistant.
• PROFESSIONAL LINE: The B+W F-Pro filter mounts have a high mechanical stability with a low overall height. They can be used on the most common wide-angle lenses without the risk of vignetting.
• Made in Germany: Schneider Kreuznach (B W) – your precision mechanics specialist for filters, photography, optics and precision for more than 100 years!

The B+W 46 mm F-Pro kaesemann high transmission circular polarizer MRC filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
