- Variable ND Filter ND2-ND400 : Adjusts light intake from 1 to 9 stops, enabling longer shutter speeds and wider apertures. This flexibility is ideal for shooting in various lighting conditions and capturing motion blur in dynamic scenes like rivers, waterfalls, and light trails. - Superior Optical Quality : Crafted with 4-element optical glass and a Japanese NITTO polarizing film, this filter ensures optimal neutrality, accurate color reproduction, and enhanced contrast for professional-grade images. - Advanced Nano Coatings : Features multiple nano coatings that minimize light reflection to just 0.1%. These coatings effectively block UV rays within the 300 nm - 380 nm range, reduce stray light and ghosting, and protect the filter from water, oil, dust, and scratches. - Ultra-Thin Metal Frame : The 9.5 mm ultra-thin metal frame allows for easy installation and prevents vignetting when used with wide-angle and telephoto lenses, enhancing compatibility across a range of photography setups. Use Cases : - Perfect for landscape photographers wanting to smooth out flowing water or create ethereal effects in bright sunlight. - Ideal for long exposure shots at twilight or nighttime to capture star trails and light streaks in urban settings. - A must-have for videographers aiming to achieve cinematic motion effects with precise control over exposure settings.
