Formatt-Hitech Firecrest 13 ND
Main Characteristics:
- 13 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
- Providing a 13 stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
- Attenuates infrared light, as well as visible and UV wavelengths, to maintain color neutrality and suppress color casts due to increased exposure lengths.
- The 15-layer Firecrest coating has been applied directly to the outside of the filter glass by way of a vacuum-formed, hard-coated, electrolytic process. The multi-coating is water- and scratch-resistance for greater overall durability.
- SCHOTT Superwite glass promotes maintained image clarity and its 2mm-thick design is compatible with the Formatt Hitech 100mm Filter Holder.
