Key Take-Aways:

The Sigma AF Cine 28-105mm T3 is the cine version of sigma-28-105-f2-8 (the Sigma 28-105mm f/2.8 DG DN Art). Sigma says it keeps that lens’s optical design and adds a limited-rotation focus ring, 0.8M pitch gears, a clickless aperture ring and a linear-motor autofocus; the L-Mount version is T3 to T22, 1.3 kg and $3,399. Jordan Drake at PetaPixel (Jul 2026), who tested it on a Panasonic S1 II with a lens supplied by Sigma, found autofocus as fast and responsive as other Sigma and Panasonic lenses, manual focus that feels mechanically coupled, and optics largely indistinguishable from the photo version apart from more flare into the sun. He called it very convenient for run-and-gun work, but said it is not parfocal and drifted dramatically while zooming, with slight breathing at the wide end and very minimal breathing at the tele end. As of Oct 2026, one written review and two videos are linked here.
