Schott optical glass lens, the image is clear.Classic paris studded border design, feel good, non-slip, easy to install.ND filter: The ND filter is called a light reduction mirror, or a medium gray density lens.
The main function is to reduce the amount of incoming light when the light is too bright, so that the camera can select the correct exposure value and avoid overexposure.
It can also “resist” a large amount of scattered light, which can improve the color saturation of the picture and make the picture more transparent.
Using a dimming mirror can also take advantage of slower shutter speeds to capture special effects such as misty water, nighttime light tracks, and more.
