Tokina 105mm Pro IRND 1.8

The Tokina 105mm Cinema PRO IRND 1.8 filter addresses infrared pollution challenges in high-sensitivity cinematography, providing precise six-stop light reduction while maintaining color accuracy. Modern cinema cameras often lack built-in infrared cut filters, requiring strong neutral density filters that can introduce color shifts and infrared contamination. This professional filter utilizes Accu-ND Technology to deliver stable color transmittance across the visible spectrum, effectively eliminating the color shifting issues common with many IRND filters.

The 105mm diameter round version features ND vapor deposition coating on both glass surfaces for high precision and optical neutrality, while the square and rectangular variants incorporate coating sandwiched between glass layers, allowing for re-polishing and extended service life. Unlike conventional IRND filters that cut near-infrared at specific wavelengths, this model employs advanced suppression technology to control infrared light up to 1200 nanometers, ensuring complete elimination of infrared pollution without compromising color fidelity.

Constructed with premium optical glass, this filter maintains consistent performance across varying lighting conditions, making it suitable for professional cinematographers working with high-sensitivity digital cinema cameras. The durable build quality ensures reliable performance in demanding production environments, with careful attention to optical precision and mechanical stability. This filter integrates seamlessly with standard 105mm filter systems and compatible cinema lenses, providing filmmakers with a practical solution for managing light exposure while preserving image quality throughout the visible spectrum. The design focuses on practical functionality for cinematography applications where maintaining true color reproduction and eliminating infrared contamination are essential requirements.
