The 62mm Formatt Hitech 62mm Firecrest ND Filter 9-Stopis a solid neutral density filter providing a 9-stop reduction in exposure. This 2.7 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.

ND 2.7 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a 9-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.

Q: 1. Will there be any color shifting in the image?

A: All ND's and particularly variable ND's can have some color shift, especially as you go darker. Since it depends on the camera, the lens, the f/stop, the light and the photographer, we cannot say for sure if you will experience color shift. Since Formatt Hitech is a well regarded company, it is our feeling that your time with the filter will likely be positive.

Q: 2. What thread pitch has this filter?

Q: 3. I'm wondering what the "stop" range on this filter is?

A: The Formatt Hitech 62mm Firecrest SuperSlim Circular Polarizer Filter, B&H # FOFCSSCP62, has a filter factor of 2.5, which would reduce 1.3 stops from your normal exposure.

Q: 4. Hi. The native Canon EF-S 24mm f/2.8 STM lens cap doesn't hold up very well on this glass. Tell me, maybe there are more suitable covers for this filter when it is not used?

A: You can try the Sensei lens cap; https://bhpho.to/2SgGWyK

Q: 5. There will be vignetting when used with Zeiss Distagon 15mm?

A: This filter will not vignette nor will that lens.

Q: 6. Will this work without vignetting with a 14mm Fuji lens that equals 21mm in full frame?

A: There should not be any vignetting, but this will still depend on the exact lens you are using. For further assistance with this question feel free to email askbh@bandh.com.

Q: 7. will this filter vignette with the Canon EF 16-35mm F4L lens?

A: You may experience vignette with this filter on the widest end of the 16-35mm Canon lens, depending on the camera you are using.

Q: 8. does this have ir control?

A: This is not for controlling Infrared light.

Q: 9. What size lens cap would I need to go in front of this?

A: The Formatt Hitech 77mm Multistop Neutral Density Filter does not have front filter threads and will not accept a standard lens cap.

Q: 10. Does the ring physically stop at min and max ends, or does it just spin all the way around?

A: The Formatt Hitech 72mm Multistop Variable Neutral Density Filter ring does not physically stop at min, or max. It does just spin around.
