The Tokina PRO IRND 1.2 Filter is a professional neutral density filter with an 82 mm diameter, designed for photographers and cinematographers who require precise light control. This 4-stop filter effectively reduces light transmission while maintaining consistent color balance, making it particularly valuable for cameras without built-in infrared cut filters. The advanced Accu-ND technology ensures consistent color transmission across the entire visible spectrum and prevents the common infrared pollution found in standard ND filters. Available in round and square designs: the round version features ND coating on both glass surfaces for optimal neutrality, while the square design embeds the coating between glass layers, allowing for multiple repolishings to maintain optical clarity. The infrared suppression technology up to 1200 nm wavelength minimizes color shifts that can occur with conventional IR cut methods. Built for professional durability, this filter preserves precise optical performance under demanding shooting conditions. The 82 mm thread ensures compatibility with numerous professional lenses and provides reliable light reduction for photography and film where exposure control and color accuracy are crucial. The neutral density properties allow for longer exposure times and wider apertures in bright light without compromising quality. Professional users appreciate the consistent performance in various lighting situations and the filter's ability to maintain true color reproduction while achieving desired exposure effects.
