Sigma 18-35mm Cine Zoom 

The Sigma 18-35mm T2 Cine High-Speed Zoom Lens with a Canon EF mount and with focus scales marked in feet 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. What sets these lenses apart from the

standard Sigma High Speed Zooms is fully luminescent markings. When shooting in dim or dark environments, focus pullers and camera operators will be able to easily discern lens markings without resorting to distracting lamps or other disruptive light sources. 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° ofrotation. All three lens control rings are geared with cine-standard 0.8 Modgears, and the focus scale is marked in feet.
