The Tokina PRO IRND 1.8 filter is an accessory with a diameter of 95 mm, designed for professional cinematography, combining infrared suppression with neutral density functions. It addresses infrared pollution issues that often occur with highly sensitive cinema cameras lacking built-in IR cut filters, utilizing Accu-ND technology for light transmission control without color shifts. This filter maintains true color fidelity across the entire visible spectrum and eliminates the need for frequent white balance adjustments during shooting or post-production corrections. Available in round as well as square or rectangular versions: the round version features ND coating on both glass surfaces for precise neutrality, while the square or rectangular type embeds the coating between glass layers, allowing for polishing to enhance scratch resistance. Unlike filters that cut infrared at specific wavelengths, this model suppresses infrared up to 1200 nm and reduces the risk of unwanted color variations. Crafted for reliability under demanding filming conditions, it supports consistent exposure control and enhances image quality for filmmakers seeking precise, neutral light control. The robust construction ensures lasting performance in professional applications, with precise manufacturing delivering uniform results across the entire filter area. The combined IRND functionality offers practical benefits through reduced equipment and simplified workflows, while the high-quality optical materials preserve image sharpness and contrast. Compatible filter holder systems allow for flexible integration into existing camera setups from various manufacturers.
