- Double anti-reflective coating
- Allows for variable light reduction; protect your lens from dust and scratches
- Decrease the depth of field by using wider apertures, which helps separate subjects from their background
- Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects such as waterfalls, clouds or any fast moving subject
- To avoid vignetting at wide angle lens, this filter has a special front lens, the diameter of the front lens is larger than that of the rear lens
