Firecrest ND is a revolutionary new type of ND filter from Formatt-Hitech. Rather than dyed resin, Firecrest is a carbon metallic coating used to create hyper neutral NDs. The filters are made from 2mm thick Schott Superwite glass, and the multicoating is bonded in the middle to increase scratch resistance. Firecrest Filters are neutral across all spectrums, including UV, visible, and infrared. This 100x100mm Firecrest ND filter reduces light by 4 stops.
Firecrest Ultra are the next generation in Neutral Density filtration for photographers.
Firecrest remains the only professional grade filter that is bonded to protect the coating in the centre of the filter giving the filter enhanced durability over coated products and protecting your investment.
With Firecrest Ultra we have taken this process one step further and we now "lap and polish" the filters, a process previously only carried out on our cinema grade filters. So as well as the superb neutrality and durability that Firecrest deliver, the filters now benefit from enhanced clarity and sharpness and are the most optically flat photographic ND filters in the world, regardless of focal length.
Firecrest Ultra are available in 100x100mm and various circular sizes and in a range of popular densities from 1 to 10 stops. 13 and 16 stops and now 18 to 24 stops.
