About Maven


Maven Optics headquarters is in America. The source of their optical components all comes from Japan, which might come as a surprise. Those of us who work in the industry know this is where some of the best glass comes from. Maven’s S, B, and RS Series use Japanese components, while the C Series uses a combination of Japanese components and optical elements from China.
