Description — Sirui 75mm T2.9 1.6x Anamorphic
The Sirui Saturn 75mm is an anamorphic prime lens built for Sony E-mount full-frame mirrorless cameras. With a fixed 75mm focal length and a maximum aperture of T2.9, it sits in the standard focal length range and is engineered for full-frame coverage, making it a capable tool for filmmakers seeking a cinematic anamorphic look. The lens is manual focus only, offering the precise, deliberate control preferred in narrative and cinematic production work.
At 1360g, it carries significant heft, so a proper support setup is recommended. The 82mm front filter thread accommodates a wide range of cinema-standard filters. There is no image stabilization, meaning shooters will want to rely on camera body stabilization or external rigs.
For Sony E-mount cinematographers working in a full-frame anamorphic workflow, the Saturn 75mm T2.9 is a dedicated, purpose-built option in Sirui's cinema lens lineup.
