Tokina 127mm PRO IRND 1.2 Filter - 4 Stops

While many of today's high-end cinema cameras lack a built-in low-pass or IR cut filter to mimic the human eye's data reception, they often require a stronger ND filter to manage exposure due to their heightened light sensitivity. This can lead to infrared pollution, a problem that many camera manufacturers suggest mitigating with an IRND filter. However, many existing IRND filters can cause unwanted side effects like color shifting. The Tokina PRO IRND 1.2 Filter - 4 Stops, a product of Kenko Tokina's innovative Accu-ND Technology, offers a solution to these challenges.

This high-quality, durable filter precisely controls the amount of light entering the lens without affecting color, thanks to its revolutionary design that stabilizes color transmittance throughout the visible spectrum. Unlike other filters, the Tokina PRO IRND filter minimizes the need for continual white balance adjustments during a shoot and subsequent color shift corrections in post-production.

Available in both round and square/rectangular styles, the Tokina PRO IRND filter features an ND vapor deposition coating. The round filter has this coating on both sides of the glass, creating a truly neutral, high-precision filter. The square/rectangular filter, on the other hand, has the coating sandwiched between two layers of glass, allowing for repeated re-polishing if scratched, thereby extending the filter's lifespan.

The Tokina PRO IRND filter stands out in the market with its unique manufacturing process. Instead of cutting the near infrared from a specific wavelength, it suppresses infrared up to 1200nm, effectively eliminating infrared pollution. This method of suppression, as opposed to cutting, is less likely to produce unwanted color shifts, making the Tokina PRO IRND filter a reliable and effective choice for professional cinematographers seeking better control over their image quality.
