Hoya HDX Antistatic UV – 72mm
With the Hoya HDX Antistatic UV of 72 mm you filter out ultraviolet light and protect the front element of your lens. UV light can cause haze and a slight blue cast, especially in landscape and mountain shots; this filter reduces that effect. With a light transmission of 98.8%, your image quality remains virtually unaffected, so you keep it on your lens permanently.
On both sides there is a 20-layer multicoating. The anti-reflective layer limits reflections, flare and ghosting for clear, sharp images. The water- and oil-repellent, stain-resistant layer repels water, fingerprints and grease, so you clean the filter easily. New is the antistatic coating: the filter does not generate static electricity, so dust clings less and you clean it less often.
The filter uses chemically strengthened L41 UV optical glass, 2 mm thick and polished on both sides. Thanks to the strengthening, the glass is more resistant to impact and breakage. You screw the filter onto your lens via the filter thread.
