Hoya’s brand new extra durable HD2 glass filters may make you jealous if you are using filters to protect your lens. Although only 1mm thick, Hoya’s lenses are significantly more durable than standard glass types. The company unveils three new filter models in the family, a low profile circular polarizer, transparent protector filter and UV filter.
Lenses with circular polarizer are often thicker because they need to rotate. When wide-angle lens is used, circular polarizers may creep into the image edges. Professional photographers would look forward to buying these ultra-durable filters to see whether their optical characteristics would match with their extreme toughness.
