Sirui Nightwalker 55mm T1.2 S35 Cine Overview

The gunmetal gray E-mount Night Walker 55mm T1.2 S35 Cine Lens from Sirui offers an ultrafast T1.2 maximum aperture that is ideal for low-light capture. Designed to cover Super35/APS-C camera sensors, this prime lens features a lightweight, compact design with high image quality, cine-style gearings, and minimal breathing. The color tone, gear position, and size are consistent across the series, providing a unified look and enabling quick lens changes when using matte boxes and other accessories.

High Optical Performance

  • Focus breathing is minimal, and aberration is strictly controlled.
Common Design Features
