The 67mm Slim Nano ND Filter from 7artisans Photoelectric has an optical density of 1.8, reducing exposure by 6 stops and allowing you to use a slower shutter speed or a wider aperture when experimenting with long-exposure shots. Designed for quick attachment, the magnetic suction filter sports an ultrathin, 2mm-thick, lightweight aluminum alloy frame that ensures the durability of the K9 optical glass and prevents wide-angle vignetting. The filter is coated with 18 double-sided nano layers that protect from water, oil, or scratch damage. Additionally, the rim is designed with threaded bezel bumps for non-slip handling.
