1.5mm slim German glass: The B270 Schott glass is manufactured in Germany and features a 22 nano-layer anti-reflection coating for better colour fidelity.

Multicoated (MC): The 6-layer protective coating is anti-static, water- and oil-repellent as well as being highly resistant to scratches and dirt.

Ultra Slim Brass Mount: The high quality Brass ring is just 2mm thick (visible), meaning that there is no vignetting, even with angle lenses over 16mm focal length. The smooth-running thread ensures that the filter is securely mounted.
