This 20mm PL mount prime is a wide focal length in the series, offering full frame sensor coverage, 6 to 8K resolution, and a T1.5 aperture in a compact, lightweight form; it is also available in Canon EF and Sony E mounts.

The 9-bladed iris produces pleasing out-of-focus bokeh effects, and ghosting and flaring have been minimized. Color reproduction is standardized for easier color correction. Each lens in the range offers consistent lens gear positions and 180° of focus barrel rotation. The FF High-Speed Primes also feature a clickless iris with linear markings, dampeners on each gear ring for silent operation, industry-standard 0.8 module gear pitch, and engraved markings for durability. Focus marks are in feet with select markings 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. If you wish to fit your FF High-Speed Prime 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 (not available for PL mounts).
