7Artisans

The 77mm Slim Nano ND Filter from 7artisans Photoelectric has an optical density of 0.9, reducing exposure by 3 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 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.
