Hoya 52mm Variable Density Filter

Original…

The 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.

The HOYA Variable Neutral Density filter can be used in place of several graded Neutral Density filters.

The Variable Neutral Density filter is helpful when:

• You need to maintain exposure control by varying the amount of light entering the camera
• Used in place of multiple graded Neutral Density filters
• Creating movement in waterfalls, rivers, and waves
• Creating motion blur of moving vehicles, trains, cars, and people
• “Panning” effect when subject maintains sharp focus while background is blurred with camera movement
