The 46mm Formatt-Hitech Firecrest ND Filter is a solid neutral density filter providing a 10-stop reduction in exposure. This 3.0 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 3.0 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.

Providing a 10-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 these filters fit the Lee 100 system holder?

A: Yes, these filters will fit the Lee Foundation Kit.

Q: 2. Can you stack this filters?

A: I stack the filter with the Fotoiox Polorizer on my Nikkoe 14-24 f 2.8 with no issues.

Q: 3. 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: 4. Is there a ND filter I can used with a 10-24mm lens that does not band or vignette? for a Tamron SP 10-24 77mm

A: This ND filter is optimized for use with wide angle lenses, so vignetting will be kept to a minimum, if there is any at all.

Q: 5. Does this have hard stops?

A: No.

Q: 6. I see that this filter has front threads. Will they securely hold my Canon lens cap?

A: Yes, the filter's front threads will hold your lens cap securely.

Q: 7. 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: 8. Will this filter block InfraRed light?

A: No, only a dedicated IR filter would work in this manner.

Q: 9. 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.

Q: 10. does this have ir control?

A: This is not for controlling Infrared light.
