Sirui Ultra Slim S-Pro Nano MC Circular Polarizer Filter (82mm) - Aluminium

Unique material

SIRUI Filter with Aluminium Rings are made with high performance aircraft aluminium 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 aluminium rings. The glass is with multiple grinding and polishing processes to meet a superior level of glass profile accuracy. High quality polarising film with nearly 100% polarisation of CPL filter has excellent neutral colour transmission for accurate colour reproduction of pictures and videos. Aircraft grade lightweight aluminium filter rings provide high strength, anti-static, corrosion resistance.

Excellent craftsmanship
In addition to the hard structure of the glass, the AR Blue-Coatings of it has nearly 100% high quality polarisation. Finest quality AR coating process with perfectly matched polarising film, helps eliminate the reflected light and extra UV protection for exceptionally clear images. 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.
