Tokina 105mm Pro IRND 1.5

The Tokina 105mm Pro IRND 1.5 filter is a professional neutral density filter designed for film shooting that requires precise exposure control. This 5-stop filter effectively regulates light transmission while addressing infrared contamination issues that often occur with highly sensitive cinema cameras. By utilizing Accu-ND technology, the filter maintains consistent color transmission across the entire visible spectrum without causing color shifts, eliminating the need for frequent white balance adjustments during shooting or extensive color corrections in post-production.

Available in round and square/rectangular designs, the filter construction varies depending on the format. The round version features an ND coating on both glass surfaces, ensuring optical neutrality and precision. The square/rectangular version employs a sandwich construction with an ND coating between two layers of glass, allowing for repeated polishing to remove surface scratches and extend product lifespan.

Unlike conventional IRND filters that completely cut off infrared at certain wavelengths, this filter suppresses infrared radiation up to 1200 nm, effectively reducing infrared contamination and minimizing the risk of unwanted color artifacts. The 105 mm filter thread size is designed for professional cinema lenses, and the 1.5 density rating provides consistent 5-stop light reduction. This filter is particularly beneficial for cameras without built-in infrared cut filters, as it helps maintain accurate color reproduction and exposure control under various lighting conditions. Its robust construction and optical precision make it suitable for professional film production environments where reliability and consistent performance are essential.
