The Hoya 40.5mm HD Protector Filter is a simple, clear filter with a 1x filter factor and is designed to provide general protection for your lens. This optically clear filter does not affect overall image quality while helping to prevent dust, scratches, moisture, and other substances from reaching or damaging your lens's front element. To prevent internal ghosting and reflections, eight layers of anti-reflection coatings are applied to each side. This total of 16 coatings offers a high degree of protection to the filter substrate and helps it to stay clean for longer than uncoated filters. The coating formula associated with HD Protector filters also promotes effective cleaning with regard to water, oil, and stains.
Constructed from chemically-hardened optical glass, the Hoya 40.5mm HD Protector Filter's resistance to scratches is enhanced while providing clarity and colour fidelity. It also features a thin, lightweight, aluminium-alloy filter ring to minimise the potential for vignetting.
