Characterized by its uniquely durable construction, the 86mm WR Ceramic Protector Filter from Sigma is a clear filter designed to guard the front of a lens from impacts, scratching, and other elements. Developed using a clear glass ceramic substrate, this filter blends a high 99.76% transmittance value with greater hardness than chemically-strengthened glass and greater flexibility than sapphire crystal glass. This results in a build that is shock- and scratch-resistant to withstand a variety of impacts while shooting. Additionally, a water-repellent coating has also been applied to resist water droplets and fingerprint smudging, as well as static electricity from attracting dust or other particles. Built for use in trying conditions, the unique design of the WR Ceramic Protector Filter helps to maintain the lens' inherent image quality while affording a high degree of protection.

Sigma WR Ceramic Protector Reviews
So clear
It's invisible glass, yet great protection for Sigma Art lenses. And some of them have rather large objective lenses that I would hate to bash.
Good buy
While it is an expensive filter nevertheless it is a good investment in protecting a much more expensive lens.

Outrageous Protection for a Lens
If you will look at Sigma's video you will see that these protectors can sustain a blow from a heavy ball bearing dropped on it from a height of three feet. The result is nothing: no crack, no breakage, not even a small ding. If you're hauling your gear around factories that have all sorts of things sticking out and smack a lens against one, the lens will sustain no damage. Furthermore, these are so resistant to scratching that I no longer use lens caps. I carry my lenses in a foam lined case and don't worry about the foam rubbing against the front element. That makes it easier and faster to switch lenses. There you go. That's why I use these on all my lenses.
