The NiSi UHC Series Filter Bundle is designed for photographers seeking high-performance lens protection and image enhancement. This bundle includes the UHC UV Protection Filter and the UHC Circular Polarizer (CPL), both crafted to ensure exceptional clarity, contrast, and durability for your photography needs. The NiSi UHC UV Protection Filter is essential for safeguarding your lens from ultraviolet (UV) light and physical damage. It features 18 layers of advanced ultra-hard coating for maximum protection and is crafted from high-purity water white glass that delivers superior light transmittance, keeping colors true to life. The ultra-slim 3.5mm knurled frame allows for easy handling and a wide angle of view, making it perfect for wide-angle lenses. Each filter comes with a protective case and cleaning cloth, ensuring your lens stays clean and ready for any shot. The UHC Circular Polarizer (CPL) enhances color and reduces reflections. It is easily adjustable via the front ring, allowing you to optimize polarization and achieve vibrant, glare-free images. This filter is perfect for landscape photography, deepening skies and enriching greens for stunning contrast and color. Constructed from high-quality AGC glass with blackened edges, and 13 advanced multi-layer coatings, the UHC CPL minimizes internal reflections and flare, maintaining crisp, clear images. Both filters in the NiSi UHC Series are built with UHD technology and double-sided high-precision polishing, ensuring sharpness even with high-megapixel sensors. The ultra-hard coating offers exceptional scratch resistance, while NiSi's multi-nano coatings make these filters waterproof, oil-proof, and smudge-resistant. This rugged design is ideal for outdoor and adventure photography, as it withstands dust, water droplets, and harsh conditions without sacrificing optical quality.
