The World's First Full Frame Auto Focus Anamorphic Cine Lens
From pioneering lightweight anamorphic lenses to launching the first full-frame autofocus, SIRUI once again pushes high-end technology further. The Astra Series-50mm, 75mm, 100mm-combines compact design with outstanding anamorphic look and efficient workflow. 44mm image circle fully covers full-frame sensors, compatible with mirrorless systems, and ready for professional cinematic production.

Solo-Ready Auto Focus
Traditional full frame anamorphic lenses rely on manual focus, which limits efficiency and requires large crews, typically for professional film teams. SIRUI Astra Series introduces fast and precise autofocus, eliminating the need for a focus puller. This significantly increases shooting efficiency, enabling solo operators or small teams to shoot professional cinema with ease.

AF / MF Switch
Switch to manual focus for precise, controllable shots. Built-in focus distance scale and LiDAR follow-focus compatibility ensure consistent focus tracking, supporting efficient and stable professional filmmaking.

Constant 1.33x Squeeze Ratio
Most mirrorless cameras shoot in 16:9. With a 1.33x squeeze ratio, this lens directly restores the classic 2.4:1 widescreen cinematic look-no cropping, no pixel loss, delivering a high-resolution! immersive image. Oval bokeh and vertical background stretch bring classic cinematic artistry to life.
