Featuring a NanoPro Multicoating on both sides of glass, the Haida NanoPro One Million X Edition ND 6.0 Filter provides a 20-stop reduction of light. This filter is mounted in an Ultra Slim Frame of only 3.1mm, and contains front threads, allowing you to use the ND Filter with other filters, such as a Circular Polarizer or Clear Protective Filter.
Ideal for wide angle lenses, the Haida NanoPro ND Filter will not cause vignetting, and ships in a protective plastic case that can be used to store the filter when not on the camera.
