GlassThe filter is made of 1.2 mm tempered glass with high resistance to impacts and scratches. That keeps the front lens element of your lens in good shape, even if you shoot outdoors often.
CoatingIrix applies 18 layers of coating to the glass. The anti reflective layer reduces lens flare and ghosting, so image contrast stays intact. A hydrophobic and oil repellent layer keeps out water, grease and fingerprints, so you wipe the filter clean quickly.
FrameThe frame is 3.7 mm thick and the filter's overall thickness comes to 5.9 mm. This slim design means you can use the filter on wide angle lenses too, without vignetting.
UseWith a light transmission of 98.9% between 420 and 750 nm, the filter lets through nearly all available light. Colours stay natural and your image stays free of haze, even in backlight.,
