Brightin Star 82mm UV Protection Lens High Transmittance Waterproof and Reflectance for 14mm Black Filter, 99.8%, Stain-Resistant, 0.048%, F2.8

------------------------------------------------------------------------------------------------------------------ 【Voltage Compatibility】 When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer. ------------------------------------------------------------------------------------------------------------------

[Multi-layer brass surface finish] The frame features a four-layer plating process. It offers excellent corrosion resistance (resistant to strong acids and alkalis) and is also heat and cold resistant (-200℃ to 260℃). The black frame is coated with a PVD hardening coating to reduce friction and ensure lubrication. Installation is smooth, and the AF nano-oleophobic layer reduces the adhesion of fingerprints and oil stains. Thanks to these layered designs, the delicate texture is maintained even after long-term use. [99.807% Transmittance Reproduces the Original Image] The transmittance of typical filters is 99.6%. At first glance, the difference may seem slight, but in actual shooting, the difference is obvious. In tests using standard image quality (without filter: 0.401 C/P), the Star AERO UV filter showed only a decrease of 0.021 C/P, with almost no loss of image clarity or resolution, achieving a depiction close to that of a bare lens. On the other hand, typical filters resulted in a resolution decrease of as much as 0.103 C/P, and a decrease in perceived resolution was visible to the naked eye. [With a reflectivity of 0.048%, reflections are no longer noticeable] The industry standard for "excellent" reflectivity is 0.1%. However, we didn't settle for that, further reducing the average reflectivity to 0.048%. This is not just a numerical improvement, but means a further reduction in stray light. Ghosting and flare are almost completely eliminated, leaving only real light and detail on the screen. [Superior Anti-Static, Waterproof, and Oil-Repellent Coating] A new anti-static coating has been added to the front of the filter. This reduces static electricity buildup, minimizing the adhesion of dust and debris to the filter. The water-repellent and oil-repellent coating makes it difficult for dirt to adhere even in harsh shooting environments, and any dirt that does adhere can be easily wiped off. There is virtually no impact on image quality even when shooting with ultra-high-resolution cameras, so you can use it with confidence in a variety of shooting situations. [Lens thickness of only 0.7mm] To match the specially designed frame, the standard 1.1mm thick glass is precisely polished down to 0.7mm. This polishing process presents significant challenges in terms of processing accuracy and yield, but by strictly controlling each step, we have achieved a process that is far more difficult than that of ordinary products. [Double-sided 28+28 layer optical grade] Cutting-edge optical technology. Using an ion sputtering coating device manufactured by OPTORUN in Japan, NanolMC nano multilayer coating is performed under high-precision control. Nano-level coating technology has traditionally been widely in high-end flagship lenses of various brands. Applying this technology to filters, it achieves reflection reduction, improved transmission efficiency, and suppression of ghosting and flare through nanostructure. [Designed for wide-angle lenses, completely eliminating vignetting] Wide-angle lenses have a very wide field of view, and light rays have a high oblique angle of incidence at the edges. When a filter is attached to the front element, a "tunnel effect" occurs due to its frame. The thicker the frame, the stronger the tunnel effect, blocking part of the light path and causing vignetting. Typical UV filters are 3.0 to 3.5 mm thick, resulting in a large tunnel effect and obstructing light entry. The Star AERO UV filter, with a thickness of only 1.5 mm, significantly reduces the tunnel effect. It completely eliminates vignetting without blocking peripheral light rays. [M System Compatibility, Strict Dimensional Control] By making the filter structure even more compact and strictly controlling dimensional accuracy, complete compatibility with genuine hoods, mount caps, and knob caps is achieved while maintaining strength. In particular, for Leica E39 and E46 standards, the structure has been pushed to the limit of tolerance, almost to the point of no margin. [The beauty of mechanical engineering lies in precision] The filter frame features a "Guilloché" pattern, a precise engraving technique once reserved only for high-end mechanical watches. A multi-layered guilloché pattern is engraved into an ultra-thin structure of just 1.5mm. Under light, it emits a mechanical texture and provides clear feedback to the fingertips. This is the result of pursuing not only appearance but also tactile feel and operability. Furthermore, it overturns the conventional wisdom that "if it's too thin, the lens cap cannot be held," and the final dimensions were determined after careful consideration and repeated polishing in a narrow space of just 1.5mm. This also achieves strong resistance to the removal of the lens cap. [Schott B270 Optical Glass Substrate, Germany] Schott, a German company with over 140 years of history, is a cornerstone of modern optical glass and can be seen in every aspect of humanity's pursuit of the ultimate field of view. They are also the manufacturer that established the de facto standard for refractive index and dispersion of optical glass. Many inexpensive UV filters use "float glass," which is intended for architecture and everyday glass products, but this is completely unsuitable for optical applications.
