It makes sense that a brand like STC Optics would make sapphire filters, yet most of the camera industry hasn't done it. Brands all across the tech world use sapphire glass. If you have an iPhone, you'll know it's supposed to be super durable.
Similarly, if you use an Apple Watch, you know how instructible your screen is. One of the most prominent uses of sapphire glass in cameras was the Leica M9-P. It's one of the things that helped cement how durable that camera has proven itself to be over the years, externally speaking, of course! We've heard about Schott glass used in filters, but we rarely hear about sapphire. So I bought a few STC Optics sapphire filters to see if they could hold up. . thephoblographer.com
