Hoya 77mm PRO ND100 Filter
Neutral density filters are designed to reduce the amount of light entering your camera lens and should not have any other effect on the image. Reducing the amount of light allows for the use of wider apertures or slower shutter speeds for creative and dramatic effect in bright lighting conditions.
The PRO ND filters use Hoya’s exclusive clear optical glass that has a metallic ACCU-ND coating front and back to create the neutral density affect.
The ACCU-ND technology in the Hoya PRO ND filters yields a truly neutral colour balance that will not add any noticeable colour-cast to your images. The Hoya PRO ND series is aimed at the still photography and HDSLR video markets.
The Metallic ACCU-ND coating on the PRO ND filters do not colour shift as you move from one density to the next, a common problem with other series of neutral density filters. Now you can set your white balance once and have the same colour balance even if you need to change filters due to changes in lighting, or for creative effect.
This 77mm PRO ND100 Filter is a dark neutral density filter with a filter factor of 100. This filter factor converts to a 6 2/3 stops light loss. This is a great filter for slowing down the shutter speed to blur motion.
