The Breakthrough Photography X4 UV Filter is designed to deliver the highest optical resolution possible while providing superior lens protection for today's highest-resolution camera systems.
Built using SCHOTT Ultrawhite B270 optical glass and advanced multi-resistant coatings, the X4 UV achieves exceptional clarity, color neutrality, and durability. The ultra-slim 3.1mm double-threaded traction frame minimizes vignetting on wide-angle lenses while maintaining compatibility with lens caps and additional filters.
Machined from brass rather than aluminum, the X4 UV offers improved durability, smoother threading, and reduced risk of binding. Its full-circumference traction texture makes installation and removal easier and more secure in the field.
