Hoya 49mm HD Nano MkII UV Filter

THE POWER OF A TITAN

The HOYA HD nano Mk II UV is the best protection you can get for your lens. Equipped with HOYA's highest quality glass, manufactured with a high-pressure press technology for maximum sturdiness, and perfected with unmatchable ultra-hard nano-coating, the HD nano Mk II UV will provide you with the protection of a fortress and an image quality worthy for the big screen. Experience what it means to use a titan!

THE UNRIVALED STRENGTH OF THE ULTRA-HARD NANO COATING

The most vulnerable spot of filters is their coatings. A coating is not permanent. Daily usage and wiping when cleaning the filter wear the coating off. The filter protects from potential physical damage – but the coating should also have extraordinary strength in order to not wear off during routine maintenance. If the coating loses its effectiveness, the image quality suffers.

But not with the HD nano Mk II's ultra-hard nano-coating. This newly developed coating is applied onto the filter's glass surface more firmly and tightly on the nano level than ever before. Due to this, the particles are layered on the glass surface with extremely high density which creates a hard-to-come-off and smooth coating.

THE ARMOR THAT IS THE HD REINFORCED OPTICAL UV-CUT GLASS

While the coating ensures the best image quality, the filter glass is essential for the actual protection of the lens. No one will shoot with a peaceful mind putting a protector filter with simple, easy breakable glass in front of an expensive lens. Even if the protector intercepts the hit, the glass might still break with the shards ending up damaging the lens anyway. What is necessary is the protection of an armor that even if it gets damaged will never shatter – just like the HD Reinforced UV-Cut Glass.

The glass of the HD nano Mk II UV is a special chemically enhanced optical glass that is a remarkable four times stronger than normal glass, making it extremely robust. However, all glass has limits to what it can withstand, and so does HD-reinforced UV-Cut Glass. In order to reduce the risk that the glass of your lens takes damage in an extreme scenario where the filter won't be able to withstand an impact, the HD nano Mk II UV will not easily shatter in all directions. Instead, it will rather stick together, avoiding the risk that shards will hit the front element of your lens.
