The 62mm Hitech Firecrest ND Filter 62mm 7-Stopis a solid neutral density filter providing a 7-stop reduction in exposure. This 2.1 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 2.1 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.

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 is set within a 5.5mm-thick SuperSlim aluminum filter ring.

Related Questions and Answers

Q: 1. 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: 2. 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: 3. Does the 100-500 lens cap fit/work on filter?

A: Unfortunately 100-500 lens cap does not fit or work on K&F Concept Nano-X Magnetic Variable ND8-ND128 Filter (77mm)

Q: 4. Can you turn the polorizer the entire way off on this filter?

A: The polarizing effect on the K&F Concept Nano-X ND2-32 Variable Fader & Circular Polarizer HD Green Coated Waterproof Anti-Scratch Japan Optics Filter (77mm) can be reduced, but not turned off.

Q: 5. Does this have threads on the front side too? I'd like to attach a lens hood

A: Yes, this does have front filter threading. You can attach a lens hood to this filter.

Q: 6. Purchased FirecrestUltra 100x100mm ND 3.0 filter. It came with some self sticking foam gasket in separate bag. There are no instructions how to install the gasket.Question: which side of the filter should the gasket be installed on? One side of the filter has writing on.

A: Put the gasket on the side that does NOT have the writing.

Q: 7. which clip-on mattebox works with this filter?

A: A rotating filter, like the Tiffen 82mm Variable Neutral Density Filter, is not compatible with clip-on matte boxes.

Q: 8. Can you stack this lens with a Hoya 55 mm UV filter?

A: Yes, the Hoya ProND EX 64 Filter (55mm, 6-Stop) has front and back 55mm threads so it can be stacked.

Q: 9. Will this filter block InfraRed light?

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

Q: 10. Does lens have lens cover threads?

A: No, this filter has no front threads.
