Hoya Filter - PROND, ND32, 72mm

Multi-layered, light-emitting neutral density filter, extends exposure by 32 times (5 stops). Reduces the amount of light that passes through the lens. The ACCU-ND technology in PROND filters gives a truly neutral color balance, even when lighting conditions change.
Suitable for shooting moving objects at slow speeds, and for avoiding overexposure of the frame.
