HOYA HD nano Mk II UV je nová osvěžená řada filtrů založená na nejnovější optické technologii HOYA.

Filtr UV Marumi z serii Super DHG.

Marumi Super DHG UV absorbs ultraviolet radiation, which gives the pictures a bluish tint.  Most effective when taking photos of objects that are far away from the camera.  The necessary filter for shooting outdoors in sunny weather (e.g. in the mountains or by the sea) where photos taken without a UV filter are usually slightly blurred.
