HOYA engineers have made a groundbreaking new development: an antistatic coating that surrounds the filter like an invisible force field and repels dust. This innovative technology ensures that your filter always remains clear and dust-free. The hardened, anti-static top layer is also water-repellent, stain and scratch resistant, and makes cleaning effortless if stains or fingerprints land on the surface. HOYA's UV filter cuts unwanted ultraviolet rays and reduces haze to improve the clarity of your images. Applied with extreme care and precision is the enhanced 18-layer Super Multi-Coating formula (on both sides). This advanced coating minimizes or eliminates reflections on the glass surface and ensures a high transmission rate for outstanding image quality. The filters are equipped with a lightweight, one-piece aluminum frame that has a flat profile. This design allows perfect parallel alignment to the sensor plane to ensure maximum sharpness. At the same time, the flat shape of the frame eliminates vignetting when used with ultra-wide angle lenses. With HOYA filters, you not only get first-class protection and optical performance, but also the certainty that your equipment is always in top condition and you can concentrate fully on your creative shots.
