The main purpose of using an ND filter is to prevent overexposure. When the light is too bright, it is difficult to select a slower shutter speed. In this case, you can use the ND filter to reduce the light entering the lens, allowing you to use a slower shutter speed for photography.

The KF ND filter effectively blocks more light, interferes with the viewfinder, ensures the quality of the shots, and can offer some dust and water protection, making it suitable for landscape photography.

The filter material is top-quality optical glass, which features a dual-sided multilayer enhanced coating that effectively reduces reflection on the filter's surface. This minimizes glare caused by the reflection of the external surroundings around the long exposure lens, ensuring top image quality.

Grinding and multi-dimensional technology is applied on both sides to balance the light penetration path and ensure that the clarity of the image is not affected.

As an additional filter on the front side of the lens, it is important to pay attention to its protective performance. The most important protective feature of the filter is its dual-sided water resistance. The surface undergoes a special water-resistance treatment. If water accidentally splashes onto the filter, the droplets will remain compact and will not scatter, making it easier to transport and clean.
