The 67mm Formatt Hitech 67mm Firecrest ND Filter - 8 Stopsis a solid neutral density filter providing an 8-stop reduction in exposure. This 2.4 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or longer shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

The design of this filter has been optimized for use with digital sensors and promote nearly flat attenuation of visible, UV, and infrared light. Due to imaging sensors' greater susceptibility to infrared light, compared to traditional film, 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 maintain truer colors and contrast. The multicoating is also scratch resistant and hydrophobic to benefit the overall durability of the filter. The filter is set within a 5.5mm-thick SuperSlim aluminum filter ring, which features front threads for stacking additional filters or attaching a lens cap.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.

Providing an 8-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 multicoating is water and scratch resistant for greater overall durability.
