The Tokina 127mm Pro IRND 1.8 filter is a professional accessory for cinematography that reduces infrared pollution while maintaining color accuracy. This neutral density filter provides a light reduction of six stops, equivalent to an ND 1.8 density, making it ideal for exposure control in bright conditions while allowing creative control over depth of field and motion blur. With Accu-ND technology, the filter ensures precise light transmission control without color shift, eliminating the need for white balance adjustments or post-production color correction. Available in a diameter of 127mm, this filter utilizes a special infrared suppression technique that controls infrared light up to 1200nm wavelength, effectively preventing the color distortion often seen with conventional IRND filters. The construction includes neutral density coating on both sides of the optical glass, maintaining stable color transmission across the entire visible spectrum. The double-sided coating design allows for immediate readiness and consistent performance. The filter is compatible with professional cinema lenses and camera systems that require 127mm filter threads. The optical glass construction offers high durability and resistance to environmental influences while preserving optical clarity under demanding production conditions. The filter's design focuses on preserving the cinematographer's artistic intent by delivering true color reproduction and eliminating infrared-induced color shifts. It serves as an essential tool for professional filmmakers in various lighting scenarios where precise exposure control and color fidelity are critical requirements.
