SIRUI has unveiled the Astra Series<\/a>. These 1.33x full-frame autofocus anamorphic lenses represent the world\u2019s first to combine a constant T1.8 aperture with fast autofocus across the entire range. Available in three focal lengths (50mm, 75mm, 100mm), each lens weighs just 600-700g and features a unified 67mm filter thread, making them remarkably portable for professional anamorphic glass.<\/p>\n Following last year\u2019s announcement<\/a> of their 20mm and 40mm S35 autofocus anamorphic lenses (40mm review here<\/a>), SIRUI is pushing the boundaries further with full-frame coverage. The Astra Series targets independent filmmakers and content creators who need anamorphic aesthetics without the traditional weight, cost, and manual-focus limitations of cinema glass.<\/p>\n The 1.33x squeeze factor on a full-frame sensor delivers an immersive widescreen aspect ratio with the characteristic horizontal lens flares and oval bokeh that define the anamorphic look. We\u2019ve seen SIRUI steadily develop its anamorphic lineup over recent years. Still, the combination of full-frame coverage, T1.8 speed, and autofocus in this package represents a clear departure from what\u2019s typically available at this price point.<\/p>\n The constant T1.8 aperture across all three focal lengths is noteworthy, particularly given the compact form factor. Traditional full-frame anamorphic lenses at this speed tend to be considerably larger and heavier. At 600-700g per lens, the Astra Series is significantly lighter than comparable manual cinema anamorphics, which often exceed 1,500-2,000g.<\/p>\n This aperture provides solid low-light performance and allows for extremely shallow depth of field when needed. The ability to separate subjects from backgrounds while maintaining the anamorphic character could prove valuable for everything from narrative work to commercial production. Of course, working wide open on anamorphic glass always requires careful focus technique, which brings us to the autofocus system.<\/p>\n SIRUI has refined its autofocus system for the Astra lenses, building on its previous Super 35 AF anamorphic work. The company claims fast, precise, and smooth autofocus performance, which should handle both run-and-gun scenarios and more controlled shooting environments.<\/p>\n Importantly, users can switch freely between AF and MF modes. The manual focus ring includes precise focus distance scales and maintains compatibility with follow focus systems and LiDAR units. This flexibility addresses a common concern with AF lenses: the need to integrate into traditional cinema workflows where manual control remains essential.<\/p>\n How well the autofocus performs in real-world shooting conditions, particularly with moving subjects or in challenging lighting, will require hands-on testing. Autofocus on anamorphic glass presents unique challenges due to the optical characteristics of the squeeze element.<\/p>\n The Astra Series launches with three focal lengths: 50mm, 75mm, and 100mm. All three lenses share similar physical dimensions, the same 67mm filter thread, and nearly identical weight. This consistency is practical for gimbal work and quick lens changes, as it eliminates the need for rebalancing between focal lengths.<\/p>\n The unified 67mm filter diameter also simplifies filter systems, though it\u2019s worth noting that using traditional circular polarizers or variable ND filters on anamorphic lenses can sometimes produce unexpected results due to the optical design. Standard ND filters should work without issue.<\/p>\n SIRUI hasn\u2019t announced wider focal lengths yet (35mm or 40mm would be typical additions), but the current range covers portraiture, medium shots, and tighter framing scenarios effectively. (We hope to see SIRUI adding an additional wider lens to this new family of lenses).<\/p>\n Mount options and compatibility<\/p>\n The Astra Series will be available in E-mount, Z-mount, and L-mount versions, covering Sony, Nikon, and Panasonic\/Leica\/SIGMA full-frame mirrorless systems. SIRUI\u2019s inclusion in the Leica L-Mount Alliance<\/a> and formal authorization to produce L-mount lenses adds credibility to their optical engineering capabilities.<\/p>\n Two distinct flare styles will be available: classic blue streaks and a more neutral light streak option. This gives cinematographers the flexibility to match different visual narratives or client preferences. We\u2019d need to see both styles in action to understand how dramatically they differ and whether one is simply a reduced version of the other or a fundamentally different optical characteristic.<\/p>\n Anamorphic flares are highly subjective, with some preferring heavy, saturated blue streaks while others opt for more subtle characteristics. Having options within the same lens series could prove valuable for rental houses and owner-operators working across different project types.<\/p>\n Warranty coverage<\/p>\n SIRUI backs the Astra Series with a 3-Year Replacement policy covering any non-user-induced issues (with valid proof of purchase), plus Lifetime Paid Repair service for accidental damage. Users need to register their lenses at sirui.com\/registration<\/a> to activate this coverage.<\/p>\n This warranty structure suggests confidence in the build quality, though the \u201cpaid repair\u201d aspect for accidental damage means it\u2019s not a complete no-questions-asked replacement program. Still, it\u2019s more comprehensive than standard manufacturer warranties.<\/p>\n SIRUI will be offering super early-bird pricing for the Astra series, starting at $799 per lens (instead of $999) or $2,399 for a set of three lenses, including a $99 hard case. Normally, this set will set you back $2,999.. <\/p>\n![\"SIRUI](\"https:\/\/www.newsbeep.com\/il\/wp-content\/uploads\/2025\/11\/SIRUI-ASTRA-5-900x506.jpeg\")
