NiSi 39mm Air UV Protection Filter with 99.9% Peak Transmission | 48 Multi-Layer Advanced ULRC Coating | Brass Frame

The NiSi 39mm Air UV Protection Filter is a premium accessory for photographers who wish to protect their camera lenses while enhancing image quality, especially during outdoor shooting. Its 99.9% transmission clarity ensures minimal impact on the amount of light reaching the camera’s sensor for clear images. This filter is designed to work with high-resolution sensors, making it suitable even for cameras with 100MP sensors without degrading image quality. Advanced 48-Layer ULRC (Ultra Low Reflection Coating) minimizes reflections and lens flare, enhancing overall image contrast and quality. By filtering out UV light 395nm, the filter helps reduce haze and blue cast in images, particularly noticeable at high altitudes and in areas with clear skies. The premium optical glass delivers exemplary image fidelity and is resistant to scratches and dirt. Ultra-thin brass frame profile reduces vignetting potential and is less likely to get stuck on the lens due to brass's higher corrosion resistance compared to aluminum. An exceptional reflectivity control helps prevent ghosting and reflections to ensure clearer images with more accurate colors. These filters are precision tested for quality and each is tested to ensure it meets high standards of quality, delivering reliable performance.

The high transmission rate ensures that there is no loss of light while taking photos. Compatibility with high-resolution sensors is a boon for professional and enthusiast photographers who demand the highest image quality. Advanced coatings not only protect against UV light but also reduce unwanted reflections, a common issue in outdoor and bright conditions. Construction from premium materials like brass and optical glass delivers durability and performance without negatively impacting image quality. The NiSi Air UV Protection Filter strikes an optimal balance between protecting your camera lens and improving photographic outcomes. The advanced multi-layer coating, high-quality construction, and attention to detail make it an exceptional choice for photographers aiming for perfection in their work. The inclusion of a storage case and cleaning cloth provide added value, ensuring that the filter remains in good condition over time.
