X4 Circular Polarizer 82mm

The Breakthrough Photography X4 Circular Polarizer at 82mm uses Schott B270 optical glass and a proprietary nano-coating to cut glare, deepen skies, and enhance color saturation without introducing color cast or sharpness loss. Built with a slim, double-threaded aluminum frame, this filter reduces light by approximately 1.5 stops and resists water, oil, and dust while maintaining minimal vignetting on wide-angle lenses. The X4 is designed for large-aperture zooms and fast primes where optical quality is critical, making it a trusted choice for landscape and travel photographers who demand professional polarizer performance.
