The Urth 82mm Base Filter Kit Pro combines UV and circular polarising filters with 34-layer CoraNano Max coatings and ultra-slim aluminium frames. The AERO-C10 glass UV filter transmits 99.28% of light with under 0.15% reflectance, while the Schott B270 glass CPL cuts polarised light from water, glass and other reflective surfaces. Rotating the CPL reduces reflections, revealing more detail and texture while maintaining natural colour.
