- Neutral density filter with a filter factor 4 (2 stops)
- Metallic accu-nd coating to minimise reflection at the filter surfaces which reduces flare and ghosting
- Helps decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
Neutral density filter with a filter factor 4 (2 stops) Grey filter that has no effect on colour balance thanks to Hoya ACCU-ND technology Metallic ACCU-ND coating to minimise reflection at the filter surfaces which reduces flare and ghosting Enables slow shutter speeds to be used to record movement in subjects such as waterfalls, clouds, cars, etc. Helps decrease depth of field by allowing wider apertures to be used, which helps separate subjects from their background
