Compact anamorphic lens with 1.33x squeeze and T1.8 stop for S35 sensors. Delivers classic anamorphic look without full-frame bulk — ideal for indie shoots with AF.
Definition
The Sirui 20mm T1.8 1.33x S35 AF Anamorphic is an anamorphic wide-angle lens from the Chinese company Sirui, specifically designed for Super 35 sensors. With its 1.33x squeeze factor, it produces the characteristic anamorphic image experience with an aspect ratio of 2.39:1 in the final image. The T1.8 aperture allows for shooting in challenging lighting conditions and creates a shallow depth of field for cinematic image composition.
The lens features autofocus functionality, which is still relatively rare in the category of anamorphic lenses. The typical anamorphic image characteristics such as oval bokeh effects, horizontal lens flares, and the characteristic distortion at the image edges are retained.
Practical Application
In German film and television production, this lens is primarily used for narrative formats, commercials, and high-quality documentaries. The 20mm focal length is particularly suitable for establishing shots, landscape shots, and dramatic wide-angle perspectives. The autofocus function simplifies working in fast-paced productions or during complex camera movements with gimbals and Steadicams.
Technical Details
The lens operates with a minimum focusing distance of approximately 85cm and features a robust metal construction. The 1.33x squeeze factor is less extreme than traditional 2x anamorphics, which reduces distortion and simplifies handling.
