This 2 to 5-stop, 67mm Freewell Variable ND Filter Kit 67mmis designed to mount onto lenses with 67mm front filter threads and provides an exposure reduction of 2 to 5-stops. Its 0.6 to 1.5 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 or add motion blur. For easier, repeatable control over density settings, the front ring is visually demarcated with numbers representing the different stop values and features side knurlings to further enable fast and precise positioning.

This filter is constructed from Schott B270 glass for enhanced clarity and color fidelity. Each glass surface is multi-coated to help eliminate internal ghosting and reflections. The Freewell 67mm Standard Day Variable Neutral Density 0.6 to 1.5 Filter is also coated for resistance to oil, dust, and scratches, offering greater protection to the filter and helping it to stay clean for longer than with uncoated filters. The coatings are hydrophobic as well, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

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

0.6 to 1.5 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 2 to 5 stops, this filter allows you to control depth of field and convey movement more easily.

Offers increased flexibility to use specific ISO settings or ISO films under bright ambient light.

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

Constructed from Schott B270 glass for increased optical clarity as well as color fidelity.

Multi-coated to prevent internal ghosting and reflections

Coated for oil, static, dirt, as well as scratch resistance and provides an improved beading effect with water for more efficient cleaning.

Aluminum alloy filter ring assembly for durability while remaining lightweight.

Side knurlings along the front filter ring allow the filter glass to be easily rotated.

Front filter ring is visually demarcated with numbers to help ensure that its rotation corresponds to the filter's exposure reduction range.

Includes storage case, magnetic lens cap, plus a microfiber cloth for cleaning and maintenance.

Related Questions and Answers

Q: 1. Do these come with the magnetic base or is that a separate purchase?

A: This Freewell 77mm Standard Day Variable Neutral Density 0.6 to 1.5 Filter would only include a magnetic lens cap.

Q: 2. Are these stackable?

A: According to Freewell it is not recommended to stack these as it and cause vignetting. Technically speaking it is possible, not recommended.

Q: 3. 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: 4. Is this VND "clear" or "off" before turning to position 2 or higher?

A: No. There is no way to turn it "off". The minimum filter factor / density would be 0.6 / 2-stops and 1.8 / 6-stops.

Q: 5. Does the kit come with a magnetic base ring 82mm?

A: No, the Freewell All-Day VND 2-5 and 6-9 stop 2-filter kit does not come with a magnetic filter ring.

Q: 6. What is included in the box beside the filters and the cap? How do you clip the filters to the lens? Does this purchase includes something like a base magnet ring?

A: Beside the filter and the magnetic lens cap, cleaning cloth and case is included. It's a screw in type lens so it has thread that connects to the lens. Only the lens cap is magnetic.

Q: 7. 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.

Q: 8. I am wondering- if you had two of these filters stacked, would you be able to safely shoot the coming eclipse?? Stop wise it would seem so. I already own one and love this filter.

A: Everything that I have read on Canon's website and the Eclipse 2017 website says NO! Regular ND filters will not work. The filter needs to be photographic filters for solar photography. The danger is damaging the camera sensor, your eyes, and the camera electronics. You want to get a White Light Solar Filter, such as made by StarGuy.

Q: 9. May i know what is the full diameter of the filter for 67mm, 72mm, 77mm, and 82mm?

A: Sorry I can't measure precisely but the system is no larger than standard filters. The diameter is about 2mm larger than the thread size and flush with the lens barrel. The magnetic system is built in to the rim of the filters so it does not take additional space.

Q: 10. can you attach another filter like a blackpro mist or moment cinebloom?

A: Theses filters do not have front threads, if the other filter you are using has front threads, then you can stack these on top.
