Sigma's FF High-Speed Prime Lenses combine the same high-quality optics and mechanics of their Global Vision still line in a cine-oriented design. This 20mm PL-mount prime is a wide focal length in the series, offering full-frame sensor coverage, 6-8K resolution, and a T1.5 aperture in a lightweight and compact form; it is also available in PL and Canon EF mounts. A common 95mm front diameter and similar physical attributes across the lens line make it easier and quicker to mount lens accessories such as matte boxes, follow focuses, and lens control motors.

• High image performance covering full frame sensors; suitable for 8K capture
• Fast T2 maximum aperture aids in shooting with low light levels
• Compact, dust- and water-resistant design with a common front diameter of 95mm across the line
• Canon EF and Sony E mounts may be swapped at an authorized Sigma service center (not available for PL mount versions)
