The 4 x 4" Ultra Cinema Graduated ND Filter from Formatt Hitech uses a rare Earth-mineral coating to create exceedingly neutral NDs. Soft-edge grads are versatile filters used to balance the luminosity of a bright sky with the terrain below. The soft edge makes it easy to place the filter in the scene, especially over undulating horizons (such as mountains). The filters are made from 4mm-thick Schott Superwite glass, and the multicoating is bonded in the middle to increase scratch resistance. Firecrest Filters are neutral across all spectrums, including UV, visible, and infrared.

Firecrest Ultra IRND are carbon-based IRND filters with hyper-neutral color balance which can be used for uniform near infrared filtration allowing your camera's color science to remain untouched. Ultra IRND are equally compatible with ARRI, RED, Blackmagic Design, Canon, Panasonic, and other modern digital cinema cameras allowing the image to be captured as the manufacturer intended.

4mm Cine Firecrest Ultra IRND have the same features of the popular 4mm Cine Firecrest ND. The 4mm Firecrest ND and 4mm Firecrest Ultra IRND both have identical optical performance with the engraving being the only difference.

Related Questions and Answers

Q: 1. can you add another B&W filter on top of this one?

A: Yes, although depending on your focal length you will start to see vignetting and potentially the edge of the filter in the corners of the frame. This will be especially true at wider angles and with more filters stacked.

Q: 2. Hi there , will this fit my 16-35mm lens ?

A: If your lens is Canon 16-35 mm f/2.8 then Yes, 82 mm is your filter size.

Q: 3. Will this work with the Canon EF 800mm f/5.6 L IS USM lens?

A: Unfortunately the Canon Drop-In Variable ND Filter A (1.5-9 Stop) is not compatible with the 800mm lens. Currently there are no variable ND filter options for the 800mm RF f5.6 lens. You can use a solid ND 52mm using the holder that comes with the 800mm lens.

Q: 4. Does anyone know the diameter of this filter's larger top area?

A: While the Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (82mm) has filter threads that connect to 82mm filters, the manufacturer does not indicate the exterior diameter of this filter in their specifications.

Q: 5. Is this filter made in Japan?

A: As per our records, the Hoya ProND EX 1000 Filter (82mm, 10-Stop) is currently made in Japan. Please note that this is subject to change at any time.

Q: 6. Up to how many stops can it provide?

A: The headline and specs both say 1.5 to 9 stops.

Q: 7. Why is it MORE expensive to buy just the filter without the adapter included?

A: While Canon sets the MSRP on their items, as of the time/date of this reply, the cost of the Canon Drop-In Variable ND Filter A (1.5-9 Stop), BH #CADIVNDFA, and the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND, on our website are currently the same price. However, I would simply recommend that if you are certain that you want the Variable ND Filter, as it is the most expensive of the filter options that are compatible for use with the Canon Drop-In Filter Mount Adapter EF-EOS R, I would simply recommend to purchase the adapter kit that comes with the Variable ND filter, the Canon Drop-In Filter Mount Adapter EF-EOS R with Variable ND Filter, BH #CAMAEFRFDIND.

Q: 8. Does the wheel have stops indicators? Or do we have to guess what stop we are at.

A: The NiSi Cinema True Color 1-5 Stop Variable Neutral Density Filter for C5 Matte Box (1 to 5-Stop) does not have stop indicators.

Q: 9. Does it have hard stops?

A: The Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (82mm) features smooth twist adjustments rather than hard stops for each stop. This allows for seamless and precise control over the amount of light reduction. The filter can be easily adjusted to achieve the desired exposure without any abrupt changes or limitations.
