Based on the popular 28-45mm F1.8 DG DN Art lens, Sigma introduces the Sony E-mount 28-45mm T2 Cine Zoom Lens with AF, a zoom lens for full-frame cinema cameras that also features autofocus. It features a 28-45mm zoom with a 1.4x magnification ratio and T2 to T16 aperture range, and it has a switch that changes the lens from manual to autofocus in a snap. Its 11-blade aperture provides a soft bokeh for a dramatic cinema look.
Its 95mm front outside diameter is compatible with numerous industry-standard matte boxes, and it accepts 86mm screw-on filters. A 1/4"-20 thread allows you to utilize optional lens mounts for a stable setup. Markings in both feet and meters makes it compatible with a wide variety of productions.
