Formatt Hitech 46mm Firecrest IRND 2.1 (7-Stop) Neutral Density Filter FC46ND2.1

  • $ 5290


  • ND 2.1 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required. Providing a 7 stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
  • Firecrest technology is hyper neutral across all spectrums, including UV, visible, and infrared.
  • 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 is set within a 5.5mm-thick SuperSlim aluminum filter ring.
  • Made in the UK on the most advanced computer-controlled manufacturing equipment in the industry.


Formatt Hitech Firecrest IRND 2.1 Neutral Density Lens Filter

TheFormatt-Hitech Firecrest IRND 2.1 Filteris a solid neutral density filter providing a 7 stop reduction in exposure. This 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.


Firecrest ND is a quantum leap improvement over all previous generation ND and IRND products and represents the technological state of the art in scientific light modification. These glass filters are hyper-neutral across the visible light spectrum and also remove more IR contamination than any other filter - making them IRND filters. 


Firecrest is a radical departure in how ND filters are manufactured. Previous generation NDs were made by dying resin. Firecrest is not a dying process, it is a rare earth metal coating process that is applied directly to the glass through an electrolytic process.


The IRND 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 multi-coating, which helps to minimize reflections and flare in order maintain truer colors and contrast. The multi-coating 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.
