The Sigma 24-35mm T2.2 FF Zoom Lens (Canon EF, Feet) combines high-quality optics and a compact form factor in a cine-oriented design. This zoom provides an image circle that covers full frame-sized sensors and produces an image quality suitable for 6K-8K capture. It features a maximum T-stop of 2.2, without any aperture ramping over the zoom range. The 24-35mm T2.2 Cine FF Zoom shares common lens gear positions with the lenses 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 24-35mm T2.2 Cine FF Zoom's lens barrel features 180° of rotation from close focus to infinity, its zoom barrel rotates 160°, and its 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 barrel is 95mm in diameter and the lens has select markings done in luminous paint for easy visibility in low light. To relieve stress on your camera's lens mount, a support foot is built into the dust- and water-resistant metal lens body, helping support the lens with the aid of a 1/4"-20 rod-mounted lens support (not included).
If you wish to fit your Cine FF Zoom lens to a different camera, the Canon EF and Sony E mount versions can be converted from one to the other by an authorized Sigma service center.
