Ideal for solar photography, this 6.6 x 6.6" Firecrest Ultra Cinema ND from Formatt Hitech uses a rare earth mineral coating to create exceedingly neutral NDs. The filter is made from 4mm thick Schott Superwite glass, with a multicoating that is bonded in the middle to increase scratch resistance. Firecrest filters are neutral across all spectrums, including UV, visible, and infrared.

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

4mm Cine Firecrest Ultra IRND have the same features as the popular 4mm Cine Firecrest ND. Firecrest Cine filters were renamed in 2019 to match the Ultra photography filters which received a new lap and polish manufacturing technique. For cinema sizes, the 4mm Firecrest ND were always lapped and polished where the 2mm photography versions were not. 4mm Firecrest ND and 4mm Firecrest Ultra IRND both have identical optical performance with the engraving being the only difference.

This filter is designed specifically for photography applications. This filter is not suitable for direct solar viewing with the naked eye, including with optical viewfinders.
