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

Eliminates reflection from nonmetallic surfaces such as water, glass, etc. Also increase contrast and colour saturation. Recommended for TTL & AF cameras and video camcoder.
