Tokina 4 x 5.65'' Cinema PRO IRND 2.4 Filter (8 Stop)

The Tokina PRO IRND filter is a revolutionary filter that stabilizes the transmittance of color throughout the visible spectrum. There are generally two types of IRND filter manufacturing processes currently in the market today. One type cuts the near infrared from a particular wavelength and the other controls rather than cuts the infrared up to 1200 nm. The Tokina PRO IRND filter is of the latter category, using suppression rather than cutting to eliminate infrared pollution. Even though both methods can be equally effective, the former type of cutting is often prone to producing unwanted color shifts. The rectangular filter has an ND vapor deposition coating sandwiched between two layers of glass so the filter can be re-polished again and again should it get scratched, extending the life of the filter.
