The Sigma 50-100mm T2 Cine High-Speed Zoom Lens comes standard in PL mount and offers an image circle suitable for Super 35mm-sized sensors. Its maximum T-stop of 2.0 remains consistent throughout the zoom range, ensuring uniform exposure. Sharing standardized lens gear positions with other Sigma High Speed Zoom lenses facilitates quick lens changes. Boasting a 9-bladed iris, the lens delivers round out-of-focus highlights for natural-looking bokeh. With 180° rotation for focus adjustment and 160° for zoom control, coupled with a clickless iris ring offering 60° rotation, precise adjustments are easily attainable. All control rings feature cine-standard 0.8 Mod gears, with focus scale markings in feet. The lens barrel's 95mm diameter accommodates a removable 1/4"-20 support foot, aiding stability when mounted on a 1/4"-20 rod-mounted lens support (not included).
