The Tokina PRO IRND 1.2 Filter is a professional 127 mm camera filter specifically designed to address infrared interference in high-quality cinema cameras. With a 4-stop neutral density rating, this filter effectively controls exposure while maintaining precise color reproduction. Thanks to Kenko Tokina's innovative Accu-ND technology, the filter regulates light transmission accurately without causing the color shifts commonly associated with traditional IRND filters. The unique manufacturing process suppresses infrared wavelengths up to 1200 nm instead of cutting them off at certain wavelengths, resulting in minimal color distortion and reduced effort for white balancing during shooting or color correction in post-production. Available in round and square/rectangular versions: the round version features ND coating on both glass surfaces for optimal neutrality, while the square/rectangular version has the coating embedded between glass layers, allowing for re-polishing in case of scratches to extend its lifespan. Made from high-quality optical glass, this durable filter offers consistent color transmission across the entire visible spectrum and reliable performance for professional cinematographers who require precise exposure control and color accuracy. The 127 mm filter diameter ensures compatibility with various professional lens systems, and its neutral density properties provide naturally appearing results without infrared contamination that can affect image quality in bright light. This filter represents a practical solution for filmmakers looking to maintain color fidelity in exposure control under challenging lighting conditions.
