The main purpose of using an ND filter is to prevent overexposure. When the light is too intense, it becomes difficult to select a slower shutter speed for photography. In this case, using an ND filter reduces the amount of light entering the lens, allowing you to use a slower shutter speed. For example, when you need to shoot in bright sunlight or want to use a longer exposure under normal lighting conditions, or capture waterfalls with a slow shutter speed to show special effects like the blurred flow of water, an ND filter is required.

The KF ND filter effectively blocks more light, affects the viewfinder, ensuring image capture quality and provides some protection against dust and water, making it ideal for landscape photography.

The filter material is high-quality optical glass, which features a double-sided multi-layer enhanced coating that effectively reduces reflections on the surface of the filter. It significantly reduces the sharp glare caused by the reflection of external light in long exposure photography, ensuring top image quality.

Grinding and polishing technology is used on both sides to balance the light passing path and ensure that the sharpness of the image is not compromised.

Since the filter is added to the front of the lens, it is even more important to pay attention to its protective performance. The most important protective feature of the filter is that it comes with dual waterproof functionality. The surface undergoes special waterproof treatment. If the filter accidentally comes into contact with water, the droplets will remain cohesive and will not disperse, making it easier to transport and clean.
