The light is not conductive in the case of the reflection of electric, so almost all non-metallic surfaces, depending on the angle of incidence more or less strongly polarized. With the circular polarizing filter (CIR-PL) can reduce unwanted light reflections and color saturation as well as contrast are improved. Blue sky will be more intense, and clouds of plastic, without the General color will be affected balance. When the Hoya merger Antistatic Professional filters an anti-static coating, which acts as a magnetic field in the reverse direction, dust and dirt from the filter to keep surface. The Hoya Antistatic Filter out due to their particular properties with far less care. The hardened, anti-static surface repels water and rain and can be easily and gently from all dirt, stains and fingerprints free. This protects the glass and prevents Scratching by the smallest dust and dirt particles. Hoya merger Antistatic Professional filters are made from hand selected silicates. By careful melting and consuming in high-quality glass components are mixed. Good workmanship and high quality materials guarantee the constant Hoya quality. The anti-static effect is achieved by a special 9-layer Super Multi-Coating formula, which also reduces reflections strong without the light transmission to affect. The low-profile aluminum filter frame is constructed in two parts and prevents vignetting. Thus, the Filter can be perfect with wide-angle lenses use.
