This 6 to 9-stop, 58mm Moment Variable ND Filter 58mm 6-9 Stopis designed to mount onto lenses with 58mm front filter threads. Its 1.8 to 2.7 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally possible. The degree of density is easily controlled by rotating the front filter ring, helping you to predetermine the additional exposure length required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily. For easier, repeatable control over density settings, the front ring is visually demarcated with lines representing the different stop values and features side knurlings to further enable fast and precise positioning. To help ensure consistent exposures, the front ring is designed to prevent any rotation beyond the stop values etched on it.

This filter is constructed from Schott B270 glass for enhanced clarity and color fidelity. To prevent internal ghosting and reflections, while further enhancing clarity and color fidelity, each glass surface includes 15 layers of antireflection coatings. The filter is also coated for resistance to oil, static, and scratches, offering greater protection to the filter and helping it stay clean for longer than with uncoated filters.

Variable neutral density filter allows you to apply differing amounts of density from scene to scene.

1.8 to 2.7 neutral density filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally possible.

Providing a reduction of 6 to 9 stops, this filter allows you to control depth of field and convey movement more easily.

This filter allows for increased flexibility to use specific ISO settings or ISO films under bright ambient light.

Filter provides increased exposure flexibility while using cinema or video cameras within a designated film frame rate.

Filter is constructed from Schott B270 glass for increased optical clarity as well as color fidelity.

15 layers of coatings on each glass surface prevent internal ghosting and reflections.

Filter is coated for oil, static, and scratch resistance.

Aluminum alloy filter ring assembly offers durability while remaining lightweight.

Side knurlings provide a more textured grip during mounting or removal.

Front filter ring is constructed to help ensure that its rotation corresponds to the filter's exposure reduction range.

Microfiber filter cloth included for filter maintenance along with a metal filter case for storage and transport.

Related Questions and Answers

Q: 1. is it possible to stack more filters on top?

A: According to information from Freewell, the front of this filter is unthreaded, meaning you won't be able to stack filters on top of it. You could mount some filters behind it, but we recommend not stacking too many as it could lead to unwanted results. Your mileage may vary.

Q: 2. is it stackable? meaning, if you wanted to stack a black pro mist on top or some there 77mm filter, can you do it? or would those have to go before the ND?

A: These are not front threaded and do not allow any filters to be attached to the front. Any additional filters you would want to use would need to go behind this filter. Though always watch out for vignetting which can happen when stacking to many filters.

Q: 3. Does it have positive stops, detents, at each of the stops?

A: The K&F Concept Variable Fader ND2-ND400 Filter (62mm) doesn't have detents; it has markings for the stops on the edge of the filter.

Q: 4. Will a stock lens cap and lens hood for a Fujifilm X-T20 fit?

A: Because the filter is a slim design with no front threads, it's likely that your stock lens cap will not securely fit. If it does manage to grab the inside of the filter, the hold would be loose as the rim is very shallow. It does come with a easy to use magnetic lens cap. As for the hood, because the filter is the same diameter front to back, it should work with most lens hoods without obstruction of the bayonet mount. However, as lens hood design vary, it's impossible to say without situational testing.

Q: 5. Do they have any noticeable color shifts?

A: We have not had reports of any noticeable color shifts when using the K&F Concept Variable Fader ND2-ND400 Filter.

Q: 6. What size slip-on cap fits the 77mm size? Spec says front is 82mm; only push on is Kaiser 82 & people say it it's not a 82mm.

A: We check the K&F Concept Variable Fader ND2-ND400 Filter (77mm) in the store and it has 82mm front threads. So you can use an 82mm front clip on filter such as this: https://bhpho.to/4aMTVOT

Q: 7. What size lens cap fits this?

A: Unfortunately, the K&F Concept Variable Fader ND2-ND400 Filter (72mm) does not have front filter threads and is not designed for use with threaded lens caps.

Q: 8. Does this filter require a magnetic base?

A: The Freewell 95mm Standard Day Variable Neutral Density 0.6 to 2.7 Filter (2 to 5-Stop) is not magnetic but has 95mm threads. Only the included cap is magnetic.

Q: 9. Does it have a front thread as well? if so, what size?

A: It does not have a front thread and cannot be stacked.

Q: 10. Do any or Freewell VND filters have IR filtration? IF so which systems and which wavelengths are filtered? Thanks

A: No, there are no Variable ND filters that are also IR that we are aware of.
