The 6.6 x 6.6" 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.

Q: 1. What size is the outside thread for a cap?

A: The front of this filter has a 46mm thread as well as the rear threads.

Q: 3. Does anyone knows what size is the larger diameter size of this filter the top part, not the 82mm the other size?, need to know to get a cap for it

A: The Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (82mm) has a front threading of 82mm. These Urth filters have the same size threading front and back for easy stacking and lens cap use.

Q: 4. Many variable neutral density filters either cause a color shift at darker settings or the dreaded "X-effect" on wide angle lenses. Does this filter suffer from those issues?

A: Any variable ND over 6-7 stops can create the X-effect. And that is the deign and physics of a variable ND filter. And it depends on the lens you are using and the light you are shooting under. As for the color shift almost all have some color shift including the Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (77mm). These are higher models of filters, https://bhpho.to/3TSB4JH

Q: 6. I think I have seen some VND's have a total size larger than its threading part, which ends up blocking the ability to mount a lens hood. Does the size of this filter prevent the mounting of a lens hood?

A: Most Variable ND filters have a larger outer diameter than the thread in size. Urth ND2-400 (1-8.6 Stop) Variable ND Lens Filter (58mm) has a front and mount thread of 58mm. However, the outer diameter of this filter is 62mm therefore if your lens hood is not wide enough it may not fit with this filter mounted on your lens.

Q: 7. I bought this VND for my sigma 16mm 1.4 lens , will it work with this lens??

A: Yes, the 67mm Urth N2-400 Variable ND filter will work with your Sigma 16mm f/1.4 lens. Due to the design of the filter front ring and the mounting style of your Sigma's bayonet hood, there might be some interference if you try to use the filter and lens hood at the same time.

Q: 8. Is this filter stackable? Can the lens cap still fit with this filter on?
