Tokina 4x4 Pro IRND 0.9

The Tokina 4x4 Pro IRND 0.9 Filter is a professional neutral density filter designed for photographers and videographers who require precise light exposure control. This square filter measures 4x4 inches (102x102 mm) and reduces light transmission by three stops while maintaining accurate color reproduction across the entire visible spectrum. With Tokina's Accu-ND technology, the filter features a neutral density coating sandwiched between two layers of high-quality optical glass, ensuring consistent performance without color shift. The filter effectively suppresses infrared light up to 1200 nm, preventing infrared pollution that can compromise image quality. This technical approach eliminates the need for frequent white balance adjustments during shooting and reduces post-production time. The robust glass construction allows for polishing in case of scratches, extending the operational lifespan of the filter. The 0.9 density offers creative control over exposure settings and depth of field under various lighting conditions, making the filter suitable for professional photography and filming applications where color accuracy and exposure precision are critical requirements.
