The Sigma 18-35mm Cine High-Speed Zoom Lens 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. The lens body is made completely of metal to stand up to the rigors of the production day. All the lenses in the lineup are designed to comply with SIGMA’s CCI standard simplifying when intercutting between lenses. Sharing the same dust-proof and splash-proof construction as the SIGMA 150-600mm F5-6.3 DG OS HSM｜Sports, each ring and mount is sealed to prevent water and dust from entering.
