The Hoya HD Mk II Protector features top-quality HD glass from HOYA, which is chemically enhanced optical glass and offers four times better protection than conventional glass. The ultra-clear glass does not affect the quality of the photograph. The anti-reflective multi-coating with high transmittance of 16 layers on both sides of the filter glass reduces the likelihood of reflections.

The coating has water-repellent and oil-repellent characteristics, making it easier to clean the filter. The glass part of the Hoya Mk II Protector is mounted with special high-pressure press technology into the frame, offering additional stability. The slim frame reduces the likelihood of vignetting, making it compatible with wide-angle lenses.

The Hoya HD Mk II Protector is one of the most robust protective filters available on the market. It is an absolutely clear filter that does not affect color balance or the quality of the photograph and lens performance. It is recommended for advanced and professional photographers who require long-lasting protection in their daily shooting.
