Rent NowThe Sirui Night Walker 24mm T1.2 S35 is a fast cine prime lens designed for Super 35mm-format cinema cameras with Sony E-mount, aimed at independent filmmakers, content creators, and hybrid shooters who want cine-style handling and an ultra-fast aperture for low-light and shallow depth-of-field cinematography. As part of Sirui’s Night Walker series, it targets filmmakers seeking affordable, manual cine primes designed specifically around Super 35 sensor coverage rather than adapted still-photo lenses.
Optically, the lens offers a 24mm focal length with an extremely fast T1.2 aperture, a T-stop rating rather than an f-stop, meaning the value reflects actual measured light transmission rather than a theoretical calculation, a distinction cinematographers rely on for consistent, predictable exposure across a matched set of lenses. This ultra-fast aperture allows for strong low-light performance and pronounced background separation, characteristics well suited to narrative filmmaking, music videos, and other productions where a shallow depth of field and cinematic rendering are priorities.
As a manual cine lens, focus and aperture are controlled entirely by hand via geared focus and iris rings, designed to work smoothly with standard follow-focus systems and gear-driven accessories common in professional video production, rather than relying on autofocus or electronic aperture control. The declicked, stepless iris ring allows for smooth, silent aperture adjustments during recording, avoiding the audible clicks and visible exposure jumps that a traditional photo-lens aperture ring would introduce mid-shot.
Build quality centers on a robust metal housing typical of cine-style lenses, with consistent front diameter and gear positioning across Sirui’s Night Walker lineup, allowing filmmakers to swap between focal lengths in the series without needing to readjust follow-focus or matte box setups. As an S35 (Super 35) format lens, it’s designed to cover Super 35-sized sensors rather than full-frame sensors, making it specifically suited to cinema cameras and mirrorless bodies using a Super 35/APS-C sensor rather than full-frame E-mount bodies.
As an E-mount cine lens, the Night Walker 24mm T1.2 S35 is compatible with Sony’s Super 35-format E-mount cameras and other E-mount cinema and mirrorless bodies operating in a Super 35/APS-C crop mode.
