This ND4 filter reduce the amount of light entering the lens so wider apertures can be selected, which is perfect for portraiture to reduce depth of field. Subject appears crisp and clear while the background becomes a soft blur. Also widely used for photographs of waterfalls and other nature scenes to emphasize movement.
The ND4 reduces light entering the camera lens by the equivalent of 2 f-stops.
This medium-class filter series was developed in the mid-2000s when digital single-lens reflex cameras were popular. Adopting digital multi-coat technology, these filters achieve an overall filter transparency of 99% (protector) with a minimum price premium. The new-concept filter series employs a black-painted frame for reduced reflection in the glass, a knurled frame for easy attachment, and other user-friendly features. These filters function well not only with digital cameras but also with film cameras.

General care and handling of the photographic filter
- Use filter carefully and always keep it clean. When cleaning use cleaning tissue or cleaning cloth. But before that remove as much dust and dirt as possible from the lens with a blower or brush.
- Avoid unnecessary cleaning of your filter.
- Filter is made of glass. When it is broken glass fragments may injure.
- Do not disassemble filter by yourself.
- When the filter is not attached to the lens, store it away from sharp objects. They may damage the filter glass.
- Keep filter away from children.
- Keep filters in plastic hard-sided case or filter pouch.
- Keep filters dry and away from direct sun light.
- Avoid storage in high humidity environment. Moisture drops due to the high humidity or dew on the filter can burn the coating and create traces on the glass surface that can be hardly wiped off.
