Unique material
SIRUI Filter with Aluminum Rings are made with high performance aircraft aluminum and top-quality German manufactured optical glass. It has the advantages of high hardness, high light transmittance and low loss. German Schott Plate Glass B270 with aluminum rings. The glass is with multiple grinding and polishing processes to meet a superior level of glass profile accuracy. SIRUI high-resolution UV filter can help you capture high definition images. Aircraft grade lightweight aluminum filter rings provide high strength, anti-static, corrosion resistance.
Excellent craftsmanship
In addition to the hard structure of the glass, the Nano-Coating process of it has almost 99.8% UV cut-off rate and helps increase light transmission to 100%. Multiple protective coatings (waterproof, oil-resistant, scratch-resistant, anti-reflective and anti-static) are applied to each side of the glass for maximum durability. Glass without coatings is highly susceptible to a range of optical phenomenon such as flaring, ghosting and generally less saturation for image. At the same time, it will easily cause damage to the lens in sudden situation. Our UV filter thickness is only 3.4mm, ultra-thin structural can prevents vignetting on wide-angle full-frame.
