Made from high quality K9 optical glass and mounted in an aerospace aluminum frame, the Interchangeable Magnetic Variable ND filter from Haida is perfect for both still photography and video.
The magnetic attachment allows you to switch out filters in just seconds, and the ND stop numbers are displayed to help ensure accurate results.
Each filter features Haida's Nano coating on both sides, resulting an image with virtually no color cast, no vignetting, and no X pattern that can sometimes be found with other variable ND filters.
