SIRUI Night Walker 24mm T1.2 cine lens

This SIRUI Night Walker 24mm T1.2 cine lens brings low light performance and cinematic control to S35 mirrorless rigs, useful for landscape, street and night filming. With a very wide T1.2 aperture you can lower ISO needs and capture cleaner night scenes while keeping shallow depth of field and attractive bokeh, making it easier to preserve detail in dim conditions.

The essentials

The Night Walker 24mm covers Super35 format and delivers the look of a roughly 34mm full frame equivalent on M4/3 cameras. It is geared towards filmmakers who want a fast prime for handheld or stabilised shooting, and it performs best when the camera is set to APSC or S35 mode to avoid vignetting on full frame bodies. Note the manufacturer advises there may be dark corners if used on full frame without switching modes.

Why it’s worth it

The lens combines a lightweight aluminium housing with a long 270° focus throw, which helps when you need fine manual focus pulls for narrative work. The standardised gear ring supports follow focus systems so you can swap lenses in the series without reconfiguring your rig. The optical design aims for minimal focus breathing and controlled aberrations, according to the manufacturer.

Who it’s for

You’ll like it if you shoot low light scenes, run S35 or M4/3 cameras such as BMPCC4K, GH5 series or GH6, and need a fast prime with close focus capability. It might not be a great match if you rely on full frame coverage without switching to crop modes, as vignetting can occur on full frame sensors.

Practical tips

Handle the lens with care despite its sturdy build, and set your camera to Super35 or APSC mode when mounting on full frame bodies to improve image coverage. The smooth focus gearing and modest weight make it a pragmatic choice for run-and-gun work and controlled studio shoots alike.
