Sigma Cine 28-105mm T3 FF Cine

40 Landscape Score
28-105mm T22 L-Mount
Why we recommend this

Constant T3 aperture across the 28-105mm zoom range and a 12-blade iris maintain exposure and soft bokeh, while the AF/MF switch brings rare autofocus to a cine lens. The 1300g build and 15.7-inch minimum focus distance offer versatile close-framing without heavy rigging, though it skips weather sealing. Best for indie filmmakers and solo shooters who need a single full-frame zoom with AF for handheld documentary or event work.

Sigma AF Cine 28-45mm T2

18.6 Landscape Score
28-45mm T16 L-Mount
Why we recommend this

The constant T2 aperture across its 28-45mm zoom range and integrated autofocus make it a flexible option for full-frame cine cameras. An 11-blade iris renders soft bokeh, and the 11.8-inch minimum focus distance delivers 1.4:1 magnification for close-up detail. It suits narrative and documentary shooters who need quick AF transitions and a compact wide-to-normal zoom without lens changes.
