The Hoya HD Mk II Protector features high-quality HD glass that is specially chemically reinforced, offering four times better protection than conventional glass. The extremely clear glass does not affect the quality of your photographs.

The 16-layer high-transmittance anti-reflective coating on both sides of the filter glass reduces potential reflections. The coating has water-repellent and oil-repellent properties, and it is stain-resistant, making it easier to clean the filter.

The glass is mounted using a special high-pressure pressing technology in the frame, providing additional stability and sturdiness to the filter. The frame is exceptionally thin, reducing the possibility of vignetting, making the filter compatible for wide-angle lenses.

The Hoya HD Mk II Protector is one of the strongest protective filters and does not affect the color balance or quality of your photographs. It is highly recommended for advanced and professional photographers who need a robust, long-lasting protector.
