7artisans Gray filter GND 0.9 - 82 mm

GND filter with graduated neutral density. Gray filter with a diameter of 82 mm. Ultra-slim frame made of aerospace aluminum. Nanotec coating. This GND filter is made of optical glass that is coated on both sides with a waterproof, scratch-resistant, and oil-repellent layer, making it easy to clean and transport. The ultra-slim aerospace aluminum frame with a non-slip CNC design can be easily mounted on the lens without vignetting or dark edges, even with wide-angle and telephoto lenses. ND filters extend exposure time. A neutral density filter (ND filter) or gray filter blocks a portion of the incoming light. With a gray filter, you significantly extend the exposure time, achieving effects such as blurred water or preventing overexposure of the image in bright sunlight with an open aperture.
