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 wider focal length in the series, offering full frame sensor coverage, 6 to 8K resolution, and a T1.5 aperature in a compact, lightweight form.
These cine-oriented primes feature clickless apertures, geared focus and iris rings, and dual focus scales marked in feet. Standardized color reproduction, common 95mm front diameters, and similar physical attributes across the line of lenses enable smooth switching between focal lengths. The lenses in this kit have fully luminescent lens markings for identifying focus and iris position in dim or dark conditions.
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 degrees of focus barrel rotation. The FF High-Speed Primes also feature 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.
