Opteka 62mm HD Multi-Coated Variable Neutral Density (2-8 Stops) Fader Glass Filter
Product Description :
The Opteka Variable Neutral Density filter is unique in the fact that it allows you to use just one filter to generate 2-8 stops of neutral density depending on how it is rotated
Enables slow shutter speeds to be used especially with high speed films to record movement in subjects such as waterfalls clouds or cars
Decreases depth of field by allowing wider apertures to be used which helps separate subjects from their background
Decreases the effective ISO of high speed film above ISO 400 and allow it to be used outdoors in bright situations
Allows cine and video cameras which have fixed shutter speeds to film subjects such as snow sand or other bright scenes which could cause overexposure
