Tokina 112mm Pro IRND 0.9

The Tokina PRO IRND 0.9 filter is a professional neutral density filter specifically designed for high-end cinema cameras that lack built-in infrared cut filters. With a precise light reduction of 3 stops (ND 0.9) and a diameter of 112 mm, this filter effectively controls light transmission while minimizing infrared pollution, which often affects digital cinematography. Thanks to Kenko Tokina's innovative Accu-ND technology, the filter maintains true color fidelity across the entire visible spectrum, without the color shifts typical of conventional IRND filters. The round version features an ND coating on both glass surfaces for highly precise neutral filtration, while the square/rectangular version employs a sandwich-like ND coating between glass layers, allowing for repeated polishing in case of scratches, significantly extending the filter's lifespan. Unlike filters that cut off infrared at specific wavelengths, this model suppresses infrared radiation up to 1200 nm and eliminates infrared contamination without unwanted color artifacts. This approach ensures consistent performance under varying lighting conditions and reduces the need for extensive white balance adjustments or post-production color correction. The filter's construction meets professional cinematography standards for durability and optical quality, making it suitable for demanding production environments where color accuracy and reliability are paramount. Available in both round and square/rectangular configurations, it offers flexibility for various camera rig setups and filter holder systems while maintaining the same optical performance characteristics.
