ARCREST II Protective Filter for Interchangeable Lenses 77mm Manufacturer's Description
ARCREST II: Approaching the lens's original rendering power to the limit.

This is a high-performance protective filter that protects your valuable lens while achieving high optical performance that minimizes the impact on images. High-quality optical glass is precisely polished flat and mounted to the filter frame using Nikon's unique mounting technology, "Flat Plane System," to maintain its flatness. Factors that adversely affect optical performance are suppressed to the utmost limit. In addition, the "Zero-One AR Coat," an ultra-low reflection AR coat with small variations in reflectance across the entire visible light range and a single-sided reflectance close to approximately 0.1, is adopted. This minimizes color balance shifts and reduces the occurrence of ghosting and flare that lead to a decrease in rendering performance. High image quality comparable to shooting without a filter can be obtained. Furthermore, an anti-static coating treatment has been newly applied to the front of the filter, reducing the adhesion of dust and debris due to static electricity. Even when shooting with ultra-high-pixel cameras, there is almost no impact on image quality, allowing for worry-free use in various shooting scenes.

AR Coat: Anti Reflection Coat

Adopts an effective anti-static coating.

A new anti-static coating is applied to the front of the filter. By making it less prone to static electricity, it effectively reduces the adhesion of dust and debris to the filter. If it does adhere, it can be easily blown away with a blower.

Adopts an excellent water-repellent and oil-repellent coating.

A unique water-repellent and oil-repellent coating developed specifically for filters is used. It is resistant to dirt such as water droplets, oil, and fingerprints, and exhibits high anti-fouling performance, allowing for easy wiping if dirt adheres. It also has high durability, having passed over 1000 wiping tests with a test load of 200g. Water-repellent and oil-repellent coatings are applied to both sides of the glass, allowing for worry-free shooting even in harsh environments.

Based on ARCREST II test conditions. Different from NIKKOR lens fluorine coating test conditions.

High optical performance achieved through meticulous attention to every detail.

Uses high-quality optical glass, also used in NIKKOR lenses, and achieves extremely high flatness of less than one interference fringe through high-precision polishing technology. Furthermore, Nikon's proprietary mounting technology "Flat Plane System" significantly reduces stress on the glass and minimizes distortion. Based on these accumulated technologies, ARCREST II is designed so that the transmitted wavefront accuracy is within λ/4 or less over approximately 85% of the filter's effective diameter. It is a high-performance protective filter that minimizes the loss of the lens's original rendering power, with optical performance enhanced through meticulous attention to every aspect.

Stripes of light and dark caused by light interference. The higher the flatness and the smaller the distortion of the surface, the fewer the number of stripes.

ARCREST II: Approaching the lens's original rendering power to the limit.

This is a high-performance protective filter that approaches the lens's original rendering power to the limit by adopting an ultra-low reflection AR coat and achieving high optical performance. It protects your valuable lens while achieving high optical performance that minimizes the impact on images.

Adopts "Zero-One AR Coat," an ultra-low reflection AR coat with a single-sided reflectance of approximately 0.1.

Using Nikon's unique technology, the "Zero-One AR Coat" is a multi-layer AR coat with an ultra-low reflectance, with a single-sided design value close to approximately 0.1 in the visible light range of 420nm to 680nm. The variation in reflectance due to wavelength differences is small, minimizing color balance shifts and reducing the occurrence of ghosting and flare. It minimizes the decrease in the lens's original rendering power caused by attaching the filter, enabling high-contrast and rich tonal image expression. There is almost no impact on rendering even when shooting nightscapes and starscapes.
