Hoya 72mm Fusion One CIR-PL Circular Polarizing Filter

When reflected on non-electrically conductive surfaces, i.e. on almost all non-metallic surfaces, the light is polarised to a greater or lesser extent depending on the angle of incidence. With the circular polarizing filter (CIR-PL) unwanted light reflections can be reduced. The Hoya Fusion Antistatic Professional filters use an antistatic coating which acts like a magnetic field in the opposite direction to keep dust and dirt away from the filter surface. The hardened, antistatic surface also repels water and rain and can be easily and gently cleaned of dirt stains and fingerprints when required. Hoya Fusion Antistatic Professional filters are made from hand-picked silicates and are therefore easy on the glass and prevent scratches caused by the smallest particles of dust and dirt. By careful melting and elaborately mixed into high-quality glass components. Optimal processing and high-quality materials enable the always constant Hoya quality The antistatic effect is achieved by a special 9-layer super multi-coating formula, which also greatly reduces reflections without impairing the light transmission. The flat aluminium filter frame is constructed in two parts and prevents vignetting. This makes the filter ideal for use with wide-angle lenses.
