The H&Y ND8 Magnetic Filter is a precise optical accessory specifically designed for the H&Y RevoRing System with compatibility for diameters ranging from 67 to 82 mm. This neutral density filter reduces light transmission by three stops, allowing photographers to achieve creative long exposure effects while maintaining optimal image quality. Made from high-quality Schott glass with a 9-layer anti-reflective coating, the filter ensures minimal color shift and maximum sharpness retention. The magnetic mounting system provides quick and secure attachment to compatible RevoRing adapters, while the nano-coating repels dust, moisture, and fingerprints for easy cleaning. With precise light reduction capabilities, this filter is particularly suitable for landscape photography, enabling extended exposure times to capture soft water movements and atmospheric effects without overexposure. The optical design preserves original color reproduction and contrast under various lighting conditions, making it a reliable tool for professional and aspiring photographers looking to expand their creative possibilities while maintaining image integrity.
