Product Description (Quoted Below):

・The Armor FX is the ultimate lens protection filter designed to withstand harsh conditions. A special polymer cushioning layer between the glass absorbs external impacts, protecting your lens.
・Traditional protection filters pose a risk of damaging the lens with shattered glass fragments if the filter breaks from impact. However, the Armor FX features an explosion-proof interlayer that holds the glass together, designed so that fragments do not scatter even if the glass breaks.
・The glass is based on water-white glass, also used in cinema square filters, and achieves high flatness through UHD (Ultra High Definition) precision polishing technology. This is a protection filter capable of handling even 8K ultra-high-definition video.
・The filter frame has a slim 3.5mm design that prevents vignetting even with ultra-wide-angle lenses of 14mm. Brass is used to ensure strength despite its thinness. Knurling is also applied for easy attachment and detachment.
・NiSi's multi-nano coating technology provides water-repellent, oil-repellent, and anti-reflective coatings, as well as a UV cut coat that absorbs ultraviolet light below 395nm, resulting in clear image quality. Despite being a multi-layer filter, it achieves a light transmittance of 99%.
