SIRUI First - Full-frame auto-focus anamorphic cine lens
From pioneering lightweight anamorphic lenses to introducing the first full-frame auto-focus, SIRUI once again continues to push high-end technology forward. The Astra series, consisting of three anamorphic cine Lens with 50mm, 75mm and 100mm focal lengths, combines compact design with outstanding anamorphic look and efficient workflow.
The 44mm image circle fully covers full-frame sensors, is compatible with mirrorless systems and ready for professional cinema production.
Solo-capable auto-focus
Traditional full-frame anamorphic Lens rely on manual focus, which limits efficiency and requires large teams, typically for professional film crews. The SIRUI Astra series introduces fast and precise autofocus and eliminates the need for a focus puller. This significantly increases shooting efficiency and allows solo operators or small teams to shoot professional cinema effortlessly.
AF/MF switch
Switch to manual focus for precise, controllable shooting.
Integrated focus distance scale and LiDAR follow focus compatibility ensure consistent focus tracking and support efficient and stable professional filmmaking.
Constant 1.33x compression ratio
Most mirrorless cameras shoot in 16:9. With a 1.33x compression ratio, this Lens directly recreates the classic 2.4:1 widescreen cinema look-no cropping, no pixel loss, and delivers a high-resolution, immersive image.
*Approximately 2.4:1 ratio
Oval bokeh and vertical background stretching bring classic cinematic artistry to life.
Shine in the dark with T1.8
Provides ample light even in low light or night scenes for high quality, clean images. The shallow depth of field creates soft bokeh and natural subject separation, effortlessly guiding the viewer's eye.
Cinematic artistry
A fusion of classic and modern
While maintaining the characteristic anamorphic character, the Astra series improves sharpness in the center of the image. Vintage edge rendition meets modern control of distortion and focus breathing, achieving a refined balance that defines true anamorphic character.
Unique backlight flare
Choose between two classic flares that emphasize the distinctive anamorphic character of the Lens and give it an unmistakable cinematic look.
Blue flare
Perfect for creating cinematic looks in sci-fi, mystery and urban environments etc.
Neutral Flare
Shows light in its natural form, suitable for daily shots, natural scenes, etc.
Outstanding close-up performance
Capture portraits and vivid close-ups with rich details with ease. The fast T1.8 aperture adds depth, texture and atmosphere.
