The Hoya HD Mk II Protector features HOYA's top-quality HD glass, a chemically strengthened optical glass that offers four times better protection than conventional glass. The ultra-clear glass does not affect the quality of your photographs.

The anti-reflective multi-coating with high transmittance of 16 layers on both sides of the filter glass significantly reduces the chances of reflections. Additionally, the coating has water-repellent and oil-repellent properties, making it easier to clean the filter.

The glass of the Hoya Mk II Protector is mounted using a special high-pressure pressing technology on the frame, providing extra stability. The frame is extremely thin, reducing the likelihood of vignetting, making the filter compatible with wide-angle lenses.

The Hoya HD Mk II Protector is one of the strongest protective filters, absolutely clear, with no impact on color balance or the quality of your photographs. It is recommended for advanced and professional photographers who need a sturdy and long-lasting protection for daily use.
