The HOYA HD Mk II PROTECTOR is equipped with HOYA's high-quality HD glass, which is a special, chemically strengthened optical glass - four times better protection than conventional glass. This ultra clear glass does not affect the quality of your photos at all.

HD COATING WITH HIGH LIGHT TRANSMISSION CAPACITY
The 16-layer non-reflective, high-transmittance multi-layer coating on both sides of the filter glass greatly reduces the chance of reflections caused by the filter. Since the coating is water- and oil-repellent and stain-resistant, cleaning the filter is easy and stress-free.

HD LOW PROFILE FRAME
The glass of the HOYA Mk II PROTECTOR is attached to the frame using a special high-pressure pressing technology, which provides additional stability, which contributes to the robustness of the filter. The frame itself is ultra-thin, which immeasurably reduces the chance of vignetting - so the filter is absolutely compatible with wide-angle lenses.

The HOYA HD Mk II PROTECTOR is one of the strongest protectors you can find. This is the ultimate clean filter that has absolutely no effect on the color balance or quality of the photo or the performance of the lens. Especially recommended for advanced and professional photographers who need an extra strong, long-lasting protector for everyday photography.
