Formatt Hitech Firecrest Ultra ND for Solar Photography (37mm, 22-Stop)
Key Features
  • 6.6 Optical Density
  • 15-Layer Coating on Outside of Filter
  • SCHOTT Superwite Glass
  • SuperSlim 5.5mm-Thick, Stackable Ring
Exhibiting improved clarity, flatness, and reduced reflectivity, this 37mm Firecrest Ultra ND for Solar Photography from Formatt Hitech is a neutral density filter providing a 22-stop reduction in exposure. This 6.6 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. Designed using inspiration from their cine Firecrest filters, these Ultra filters receive an additional lapping and polishing process during production to ensure lower reflectivity and improved clarity and sharpness.

Asked by: John
Yes, when shooting in live view, you can use it. I wouldn't use it while looking through the viewfinder if you have a DSLR but live view is ok.

Will this work with the smallrig Lightweight Matte Box? I see many people saying 100x100mm are incompatible but they say 4x4 inch are... confusing or what??
Asked by: David
The Formatt Hitech 100 x 100mm Firecrest Ultra ND 0.9 Filter (3-Stop) is incompatible with the SmallRig Lightweight Carbon Fiber Matte Box because the filter trays on the matte box support 4mm thick filters, and the Formatt Hitech filter is 2mm thick.

Is this filter rated as a solar filter suitable for photographing the sun?
Asked by: Douglas
Formatt Hitech 105mm Firecrest Ultra ND 5.4 Filter (18-Stop) does not have an ISO rating for safe solar viewing. It may work for a camera as it is not sensitive as human eyes, but if you want to be 100% safe I would recommend looking for a filter that is listed with an ISO rating for safe solar viewing.
