Features
1.1mm Schott B270 optical glass polished to a flatness of ±20μm. Chemically strengthened to withstand impact of 350MPa (equivalent to dropping a golf ball three times from a height of 120cm.) The rim has been carbon blackened, reducing ghost images by absorbing reflectivity and diffused infrared within the lens.
Patented Ultra Layer coating blocks UV light below 395nm, preventing haze and color cast in your images. Does your UV filter product really work? Check here
This double-sided anti-reflective coating raises transmission to 99.38% with reflectivity below 0.3%.
For the rim, we use a tough but lightweight aluminum alloy frame. The slim pressure ring design can allow as much light in as possible and also reduces vignetting when using a wide-angle lens. The inner circle is treated with non-stick Teflon and a matte black finish and the embossed frame is easy to rotate, won’t jam and cuts out reflection. The shock-absorbent frame also reduces the chance of damage to your lens if it takes a knock. We also offer a factory lifetime warranty and repair service for the frame and innovative maintenance services for the lens.
