SIRUI Astra Series Review: The First Autofocus Anamorphic Cine Lens?
Anamorphic lenses have always meant a trade-off: the classic widescreen look and oval bokeh cinematographers love, but manual-focus-only operation that requires a dedicated focus puller on set. The SIRUI Astra Series is built to remove that trade-off. SIRUI calls it the world’s first full-frame autofocus anamorphic cine lens, and after digging into the specs and feature set, it’s easy to see why solo shooters and small crews are paying attention.
SIRUI Astra Series: Quick Overview
The Astra Series ships in three focal lengths, 50mm, 75mm, and 100mm, all at a T1.8 fast aperture with a constant 1.33x squeeze ratio. That squeeze ratio matters because it restores a roughly 2.4:1 cinematic widescreen image from a standard 16:9 sensor with no cropping and no pixel loss. Each lens covers a full-frame sensor and is available in Sony E and Leica L mounts, with broad compatibility across Sony Alpha/FX cameras, Panasonic Lumix S-series, Sigma fp bodies, and Leica SL cameras.
Key Features
- Solo-ready autofocus: A built-in AF/MF switch lets you shoot with fast, precise autofocus or flip to manual control, with a focus distance scale and LiDAR follow-focus compatibility for consistent tracking.
- True anamorphic character: 18 elements in 14 groups (50mm), including 4 cylindrical lenses, deliver oval bokeh and vertical background stretch, plus a choice of Blue or Neutral flare styling.
- Fast T1.8 aperture: Enough light for low-light and night scenes, with a shallow depth of field for natural subject separation.
- Consistent set matching: Uniform color and tone across all three focal lengths for fast lens swaps and easier color grading in post.
- Built to work: Aluminum alloy housing with triple protection (dustproof, dirt-resistant, raindrop-resistant), a 67mm filter thread, and identical gear positioning across the set.
Who Is the SIRUI Astra Series For?
This lens series is aimed at independent filmmakers, content creators, and small production teams who want the cinematic anamorphic look without the crew size a fully manual anamorphic setup usually demands. The autofocus system in particular makes it realistic for solo shooters and run-and-gun documentary or narrative work, while the T1.8 aperture and full-frame coverage keep it relevant for higher-end mirrorless cinema setups.
Pricing
A single SIRUI Astra lens starts at $849 for one focal length in your choice of mount and flare style, with the full 50/75/100mm three-lens set also available as a bundle for shooters who want consistent color and character across their whole kit. Every lens ships with a carrying bag, lens cap, cleaning cloth, and warranty card, and SIRUI backs the Astra Series with a 3-year replacement warranty for non-human damage plus lifetime paid repair service.
Pros and Cons
Pros: genuine autofocus on an anamorphic cine lens (a rare combination), fast T1.8 aperture, full-frame coverage with no cropping, consistent look across the focal length set, broad camera compatibility, solid build quality with weather protection.
Cons: anamorphic lenses remain a specialized investment at this price point, the AF system is tuned for anamorphic workflows rather than general photography, and buyers need to pick mount and flare style carefully since those aren’t interchangeable after purchase.
