Kolari Vision Pro IRND Filter (86mm, 20-Stop)

This 20-stop, 86mm Kolari Vision Pro IRND Filter is optically engineered to be the most neutral filter in the visible light spectrum and beyond into the infrared range. This filter delivers neutral darkening in every wavelength, at every angle, and it is suitable for use in creating long-exposure photographic effects. Ultrawide angle tested and approved for excellent vignetting and color cast performance. Built with premium ultrathin, ultra-strong Corning Gorilla Glass, this filter is more than two times stronger than Schott B270 glass to direct impacts, and more resistant to scratches for better long-term durability. The slim-brass frame features knurling that helps with your grip, making it easier to attach and remove the filter.
