Precision OpticsCrafted from top-tier Japanese optical glass with double-sided 24-layer enhanced coating, this filter reduces surface reflections effectively. This prevents glare caused by external reflections during prolonged exposures, ensuring impeccable image quality. ^^ Enhanced Water ResistanceFeaturing a multi-layer waterproof coating, even if water splashes onto the filter, it remains in droplet form, allowing for easy carrying and cleaning. ^^ Versatile Light ControlWith 1 to 9 stops of adjustable light reduction and 360-degree rotation for precise dimming settings, this filter is perfect for diverse scenarios.
(Note: High settings may cause a cross-pattern effect, commonly known as a "black cross.
