The SIRUI Astra 100mm T1.8 is part of SIRUI's first full-frame autofocus anamorphic cine lens series, here in Sony E mount with the Neutral Flare coating. It gives a tighter telephoto view for compressed close-ups, details and isolating subjects, combining the oval bokeh and widescreen character of anamorphic glass with fast, reliable autofocus.

Most mirrorless cameras record 16:9. With a constant 1.33x squeeze, Astra restores the classic 2.4:1 cinematic frame straight from the sensor, with no cropping and no pixel loss. The T1.8 aperture keeps images clean in low light and gives shallow depth of field for natural subject separation.

Key Features

  • Fast, precise autofocus with AF/MF switch: shoot anamorphic solo or with a small crew, no focus puller needed
  • Constant 1.33x squeeze: de-squeezes 16:9 to a 2.4:1 widescreen frame with no cropping or lost resolution
  • Full-frame coverage with a 44mm image circle, also suits Super 35 and APS-C
  • Neutral Flare: natural, understated flares for everyday, documentary and natural scenes
  • Oval bokeh and vertical background stretch, with improved centre sharpness and controlled distortion and focus breathing
  • FN button for AF lock or a custom function
  • Iris lock: lock at A for camera-controlled aperture, or unlock for manual aperture on the lens
  • Click on/off switch for stepped or smooth (de-clicked) aperture
  • Feet/metre focus scale, compatible with LiDAR follow-focus systems
  • Identical gear positions and matched colour across the 50, 75 and 100mm
  • Aluminium alloy body, dustproof, dirt-resistant and raindrop-resistant
  • 13-blade aperture, T1.8 to T22
