The Tokina Cinema 50-135mm T3.0 delivers a highly versatile zoom range in a compact design. Tokina engineers have created a lens that is Parfocal, has dramatically reduced breathing and image shift, and a de-clicked, 9-bladed, curved iris for beautiful bokeh and precise exposure control. With its 1M close-focus capability, the lens allows you the freedom to capture a tight close-ups while maintaining a comfortable distance from your subject.
