This feature is particularly beneficial for outdoor photographers who face challenging environments and need their gear to perform without fail.At the heart of the X4 Uv Filter is the critically sharp Schott B270 Ultrawhite optical glass, manufactured in Germany. Renowned for its durability and high-quality performance, this glass ensures that your images remain unaffected by the adverse effects of Uv light, such as lens flare and haziness.The X4 Uv Filter's design is a testament to Breakthrough Photography's commitment to innovation. The ultra-slim, double-threaded 3.2mm Traction Frame is not only lightweight but also engineered to prevent vignetting on full-frame wide-angle lenses.
