Technical Specifications

The Sirui Astra series are the world's first full-frame anamorphic lenses with autofocus and T1.8. Three focal lengths (50mm, 75mm, 100mm) with an identical 67mm filter diameter and a 1.33x squeeze factor deliver a 2.35:1 final aspect ratio on 16:9 sensors. Two flare variants available: Classic Blue Streak or Neutral. Switching between AF and manual focus is possible, distance scale is compatible with follow focus and LiDAR.

Applications

The Astra series enables an anamorphic cinematic look even on a limited budget. Their compact design and autofocus make them ideal for gimbal, run-and-gun, and documentary work. The 1.33x factor produces subtler oval bokeh circles than 2x anamorphic lenses and more natural facial proportions.
