Variable Neutral Density Size:77mm Although the aperture becomes oneThe Hoya Variable Neutral Density Filter provides a way to maintain exposure control by varying the amount of light entering the camera by 1. 5 to 9 stops (0. 45 to 2. 7 density for cinematic use). The precision built in double ring design allows the outer ring to rotate to control the amount of neutral density effect anywhere within the 1. 5 9 stop range. This double ring design is thin to reduce the likelihood of vignetting with wide angle lenses.
