1.5mm slim German glass                 
The B270 Schott glass is manufactured in Germany and features a 22 nano-layer anti-reflection coating for better color 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 Aluminum Fixing                 
The high quality aluminum 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.                 
                
• Extremely thin - only 2mm. No vignetting even with wide-angle lenses (f=16mm)                 
• German manufactured Schott Plate Glass B270 with 22 layer Anti-Reflective Coating on both surfaces to reduce reflections and provide light transmission above 99%                 
• Six layer protective coating (waterproof, oil-resistant, scratch-resistant, anti-reflective, anti-static) for easy cleaning and superior lens protection                 
• Lightweight, high performance "scientific grade" aluminum filter ring provides high strength, corrosion resistance, stability and critical filter alignment                 
                
Available in the following sizes:                 
40.5mm, 49mm, 52mm, 55mm, 58mm, 62mm, 67mm, 72mm, 77mm, 82mm
