1-5 f-stops ND: K&F CONCEPT Variable ND2-32 filter helps you achieve your desired exposure in changing light, excellent for videography and landscape photography. Precision Optics: Made of high quality optical glass with double-sided 24-layer enhanced coating, this filter effectively reduces surface reflections. This prevents glare caused by external reflections during long exposures, ensuring flawless image quality. Versatile Light Control: 360-degree rotation for precise dimming settings, capable of reducing light at different apertures to achieve balanced exposure and capture long exposures. Nano Coating: The ND filters are coated with a dustproof, scratch-resistant, oil-resistant and colour-neutral layer to provide the best possible image quality when shooting outdoors. Slim and Secure: The frame is only 7.4mm thick and has a CNC trapezoidal pattern design that increases rotational friction and is convenient for installation and removal.
