The Sigma 18-35mm T2 Cine High-Speed Zoom Lens with focus scales marked in feet and normal luminous scale markings provides an image circle that covers Super 35mm-sized sensors. It features a maximum T-stop of 2, and the aperture does not ramp over the zoom range. It shares common lens gear positions with the other lens in the Sigma High-Speed Zoom lineup, which makes for rapid lens changes.
The 9-bladed iris provides round out-of-focus highlights for a natural-looking bokeh. The lens barrel features 180° of rotation from close focus to infinity, the zoom barrel rotates 160°, and the clickless iris ring features 60° of rotation. All three lens control rings are geared with cine-standard 0.8 Mod gears, and the focus scale is marked in feet. The front of the lens is 95mm in diameter with a removable 1/4"-20 support foot that helps support the lens with the aid of a 1/4"-20 rod-mounted lens support (not included).
