Sirui Astra T1.8 1.33x AF Anamorphic 50mm
A constant T1.8 aperture across three anamorphic focal lengths—50mm, 75mm, and 100mm—on full-frame Sony E mount with selectable autofocus enables 2.4:1 widescreen shooting without cropping. Neutral streak flares and a consistent 44mm image circle deliver a unified, subtle cinematic look, while the shared 67mm filter thread streamlines rig changes. This kit is ideal for indie filmmakers and Sony hybrid shooters who need a compact, autofocus-capable anamorphic set for run-and-gun video with natural flare character.
