Sirui's anamorphic cine prime for Sony E — the Saturn 35mm for full-frame anamorphic widescreen.
The Sirui Saturn 35mm T2.9 1.6x Full-Frame Anamorphic is a cinema lens for Sony E-mount that creates genuine anamorphic widescreen images on full-frame sensors. Unlike the MFT Sirui anamorphics, the Saturn series covers full frame with a 1.6x squeeze ratio. The T2.9 rating measures actual light transmission rather than the theoretical f-stop.
The 1.6x anamorphic squeeze produces a 2.4:1 widescreen aspect ratio when de-squeezed in post. Anamorphic characteristics include horizontal lens flares, oval bokeh, and the distinctive cinematic rendering associated with high-end film production. Sharpness is good in the centre with intentional anamorphic softness at the edges. The full-frame coverage is notable.
Sony E mount. Filter thread varies by version. Weight is approximately 800 grams. Build quality is cinema-grade with geared focus ring for follow-focus systems, de-clicked aperture iris, and consistent front diameter across the Saturn set. Manual focus only. The T-stop aperture marking ensures exposure consistency — essential for cinema production.
Limited availability on the used market. Check geared ring smoothness and optical alignment. An affordable entry to full-frame anamorphic cinematography — professional cinema anamorphic lenses cost tens of thousands. The Saturn series makes the distinctive anamorphic look accessible to indie filmmakers and content creators.
