[ARCREST II: Approaching the Lens' Original Image Quality to the Extreme] This high-performance protective filter approaches the lens's original image quality to the extreme through the adoption of an ultra-low reflection AR coating and the realization of high optical performance. It protects your valuable lens while achieving high optical performance that minimizes the impact on the image.
[Features "Zero One AR Coating," an ultra-low reflectivity AR coating with a single-sided reflectivity of approximately 0.1%] The "Zero One AR Coating" is an ultra-low reflectivity AR coating with minimal variation in reflectivity across the entire visible light spectrum, bringing the single-sided reflectivity close to approximately 0.1%. This minimizes color balance distortion and reduces the occurrence of ghosting and flare that can degrade image quality. High image quality comparable to that achieved without a filter is obtained.
[Achieving high flatness polishing accuracy with fewer than one interference fringe] High-quality optical glass is precisely polished to a flat surface and mounted to the filter frame using Nikon's unique "Flat Plane System" mounting technology to maintain its flatness. The occurrence of factors that negatively affect optical performance is minimized to the greatest extent possible.
[Effective anti-static coating adopted] A new anti-static coating has been adopted on the front of the filter. This makes it less prone to static electricity, reducing the adhesion of dust and debris to the filter.
[Features a superior water- and oil-repellent coating] The water- 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 away. It has virtually no impact on image quality, even when shooting with ultra-high-resolution cameras, allowing you to use it with confidence in a variety of shooting situations.
