When reflected on non-electrically conductive, i.e. almost all non-metallic surfaces, the light is more or less strongly polarised, depending on the angle of incidence. The Circular Polarizing Filter (CIR-PL) reduces unwanted light reflections and improves color saturation and contrast. Blue skies become more intense and clouds become more vivid without affecting the overall color balance.

Hoya Fusion Antistatic Professional filters use an antistatic coating that acts like a magnetic field in the opposite direction to keep dust and dirt away from the filter surface.

The Hoya Antistatic filters require far less maintenance due to their special properties. The hardened, antistatic surface also repels water and rain and can be easily and gently cleaned of stains and fingerprints if necessary. This protects the glass and prevents scratching by the smallest dust and dirt particles.
Hoya Fusion Antistatic Professional filters are made of handpicked silicates. Through careful melting and elaborate mixing into high-quality glass components. Good workmanship and high-quality materials guarantee the constant Hoya quality.

The antistatic effect is achieved by a special 9-layer super-multi-coating formula, which also greatly reduces reflections without impairing light transmission. The flat aluminium filter frame is constructed in two parts and prevents vignetting. This makes the filter perfect for use with wide-angle lenses.
