Japanese glass manufacturer Hoya says it has created a new coating that prevents dust, water and fingerprints from sticking to the surface of its filters. The company claims the coating acts like a 'force field' around its new Fusion series of filters, protecting them from stains as well as scratches. The idea of the coating is to make the filters easy to clean and to reduce the chance of damage while in use or storage.

The coating is said to consist of nine layers that work to reduce reflections from the surfaces of the glass and which aim to allow as much light through to the lens as possible. Hoya says the coating has 'virtually no effect' on the color balance, contrast, clarity or exposure of the final image.

The first Fusion filters will be for cutting UV, a circular polarizer and a plain protector glass. They are available in screw-in sizes from 37mm to 105mm (to 82mm in the UK) and come mounted in slim low-profile frames that are said to avoid interfering with the corners of images shot with wide angle lenses.
