Sirui Astra Series T1.8 1.33x 50mm Full-Frame Anamorphic 50mm
The autofocus-capable 1.33x anamorphic design covers full-frame with a 44mm image circle and a fast T1.8 aperture, delivering a 2.4:1 widescreen ratio without cropping. Neutral streak flares and oval bokeh provide a natural cinematic look, while selectable manual/autofocus and a light 635g body enhance on-set adaptability. Best for Sony E-mount filmmakers needing dependable autofocus for portrait and narrative work on gimbals, where the close 1.6-foot minimum focus distance adds creative framing.
