With a 16x filter factor that reduces exposure by 4 stops, this 100 x 150mm NanoPro MC Hard Edge Graduated Filter from Haida is designed to darken select portions of your image without affecting image sharpness or color reproduction. It features a hard edge in its center that starkly divides the clear section and the darkened section, making this filter ideal for photos with a sharp horizon such as seascapes and elevated urban landscapes.
The NanoPro MC is made of optical glass and features a 2mm thickness compatible with a wide range of holders. Both sides of the filter are treated with several layers of coating, resulting in minimized reflections and increased resistance to scratches. The multicoated construction also makes it easier to clean water and other debris from the glass surface, suiting it for use in the outdoors.
