The SIRUI Astra 75mm T1.8 1.33x Anamorphic is part of Sirui’s breakthrough lineup of full-frame autofocus anamorphic cine lenses — the first of their kind to combine true anamorphic optics with fast, reliable autofocus in a lightweight, production-friendly package.
Unlike many anamorphic lenses limited to Super 35 coverage, the Astra series fully covers full-frame sensors with a generous 44 mm image circle, making this 75 mm model an excellent choice for modern mirrorless cinema workflows without heavy cropping or unexpected vignetting.
This lens combines the classic anamorphic aesthetic — sweeping horizontal field of view, cinematic aspect ratio, and expressive flares — with practical autofocus and modern mechanics that benefit both solo operators and small crews shooting across Bangkok, Phuket, Chiang Mai, Pattaya, Samui, and nationwide productions.

Full-Frame Cinematic Coverage
Designed to cover full-frame sensors with a 44 mm image circle — ideal for mirrorless cinema cameras shooting large formats without edge fall-off or vignetting.
Autofocus + Manual Options
Smooth autofocus via STM motor with AF/MF switch, as well as compatibility with LiDAR and other follow-focus systems. Precise focus tracking supports confident shooting with moving subjects.
Anamorphic Character
Constant 1.33x squeeze yields a cinematic widescreen aspect ratio and classic anamorphic look — horizontal compression, elegant oval bokeh, and expressive flare behavior.
