Exhibiting improved clarity, flatness, and reduced reflectivity, this 3-Stop, 100 x 150mm Formatt Hitech Firecrest Ultra Hard Edge ND Filter 100x150mmis ideal for photographing landscapes or other subjects with a defined horizon and which require an extra level of control over your exposure.

Designed with inspiration from the Firecrest Cine filters, these filters receive an additional lapping and polishing process during production to ensure lower reflectivity and improved clarity and sharpness. This filter has also been optimized for use with digital sensors and promotes nearly flat attenuation of visible, UV, and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film stock, color casts can occur when photographing darker subjects that require increased exposure times. This filter provides a high level of neutrality across all three spectrums in order to eliminate color casts and ensure cleaner, truer blacks.

Applied to the outside of the Schott Superwite glass construction is a 15-layer Firecrest multicoating, which helps to minimize reflections and flare in order to maintain truer colors and contrast. The multicoating is also scratch resistant and hydrophobic to benefit the overall durability of the filter. Measuring at 100 x 150mm and 2mm thick, this filter is compatible with the Formatt-Hitech 100mm Filter Holder.

The Ultra Firecrest series of filters exhibit greater clarity and have lower reflectivity than the original Firecrest filters. Borrowing from the range of Firecrest Cine filters, the Ultra series filters undergo a secondary lapping and polishing process after the initial polishing and bonding stage. This additional step helps to ensure flatness and consistency for improved image quality.

The 0.9 density provides a 3-stop reduction in light in selective areas.

This filter 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 multicoating is water and scratch resistant 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.
