The black RF-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.
Ideal for Low-Light Shooting
  • The maximum T1.2 aperture enables you to capture low-light scenes using lower camera ISO settings.
  • Ideal for run-and-gun filmmakers.
Longer Prime
  • This longer 55mm lens in the Night Walker series is ideal for close-ups and portrait shots.
High Optical Performance
  • ED (extra-low dispersion) and high refractive index glass elements contribute to this lens' high optical quality.
  • Focus breathing is minimal, and aberration is strictly controlled.
Common Design Features
  • Lenses in the Sirui Night Walker cine lens series share common focus and iris gear ring positions.
  • Enables quick lens changes by reducing the need for follow focus units or iris motors to be repositioned.
Compact Form
  • This prime lens features a compact, lightweight design.
  • The aluminum alloy construction helps to protect the inner optical elements.
Focus Marks
  • Focus markings and measurements are provided in both feet and meters.
