K&F Concept 55mm Variable ND Filter ND3-ND1000

Ultra-thin HD Filter with Double-sided 28-layer Nano-coating, Nano-X Series

• Ultra-high-definition imaging: Constructed from premium Japanese optical glass with oxidized and sandblasted surfaces. Features double-sided multi-layer enhanced coating combined with advanced grinding and polishing technology to effectively reduce surface reflections. This minimizes glare caused by external light reflections during long exposures, ensuring ultra-high-definition image quality.
• Double-sided nano-coating: Equipped with 28 layers of nano-coating on both sides, providing waterproof, oil-proof, and scratch-resistant protection. This coating prevents wind and debris from scratching the lens surface. Water droplets bead up without spreading, facilitating easy cleaning and offering anti-fog properties during long-term storage.
• Variable ND range ND3 to ND1000: Allows smooth adjustment of light reduction from ND3 to ND1000. The filter frame includes a push rod mechanism for convenient gear size adjustment. This feature is especially beneficial for videographers who require precise and automatic light reduction control using auxiliary tools.
• Convenient storage: Comes with a dedicated storage bag designed with a side-pull structure inspired by square storage bag styles, making it easy to carry and quickly access the filter during outdoor shooting sessions.
