SIRUI Venus 50mm T2.9 1.6x Full-Frame Anamorphic [Sony E Mount]

The SIRUI Venus 50mm T2.9 1.6x Full-Frame Anamorphic is a manual cinema lens for Sony E-mount cameras that combines a natural mid-range perspective with pronounced anamorphic rendering. It covers full-frame sensors and uses a 1.6× horizontal squeeze, giving the image a wider cinematic field of view together with stretched oval bokeh and horizontal blue flare. The 50 mm focal length sits between the wider 35 mm and more compressed 75 mm versions, making it a versatile option for dialogue scenes, medium shots, portraits and general narrative work.

Full-frame 1.6× anamorphic image

The 1.6× squeeze expands the horizontal composition after de-squeezing while preserving the vertical perspective of a 50 mm lens. On a 3:2 recording area, the de-squeezed image can reach approximately 2.4:1, while 16:9 acquisition produces an approximately 2.8:1 frame. The horizontal field of view is comparable to roughly a 31 mm spherical lens, giving the Venus 50 mm a useful balance between environmental context and subject separation.

Classic blue streaks and stretched oval bokeh

Bright point sources can generate the characteristic horizontal blue streaks associated with the Venus series. The 10-blade iris and 1.6× squeeze create elongated oval highlights in out-of-focus areas, helping give footage a recognizably anamorphic character. The lens uses 16 optical elements in 13 groups and is color-matched to other Venus focal lengths, which helps maintain a consistent look when changing lenses within the series.

T2.9–T16 manual cinema aperture

The 50 mm has a maximum aperture of T2.9 and closes to T16. It is fully manual, with no autofocus, image stabilization or electronic communication with the camera body. The focus and aperture controls are designed for cinema use, and the focus ring provides approximately 95.5 degrees of rotation. This allows the lens to integrate easily with manual or wireless follow-focus systems during narrative, commercial and music-video production.

Closer focusing than the 35 mm version

Minimum focus distance is approximately 0.75 m, allowing the 50 mm to move closer to a subject than the 35 mm Venus while retaining full-frame anamorphic coverage. The front filter thread is 82 mm, simplifying the use of screw-in ND, diffusion or polarizing filters. The aluminium-alloy cinema housing also incorporates consistent geared control positions across the Venus range, helping speed up lens changes in a rigged camera setup.

Built for supported cinema rigs

The Sony E-mount version weighs approximately 1.03 kg. A lens-support mounting point can therefore be useful when the camera is built around 15 mm rods, a matte box or a wireless focus system. The robust all-metal construction makes the lens well suited to controlled production environments where repeatable focus and iris operation are more important than autofocus convenience.
