SIRUI has unveiled the Astra Series. These 1.33x full-frame autofocus anamorphic lenses represent the world’s 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. Following last year’s announcement of their 20mm and 40mm S35 autofocus anamorphic lenses (40mm review here), 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. 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’ve 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’s typically available at this price point. SIRUI Astra 50mm.

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. This aperture provides solid low-light performance and allows for extremely shallow depth of field when needed. The ability to separate...
