Sirui's wide-angle cinema prime for APS-C — the 24mm T1.2 Nightwalker for low-light filming.
The Sirui Nightwalker 24mm T1.2 is a wide-angle cinema prime from Sirui's Nightwalker series for APS-C mirrorless cameras. At 24mm on APS-C, it provides a 36mm equivalent field of view — a classic wide-normal perspective ideal for establishing shots, interviews, and general video work. The T1.2 aperture makes it extremely capable in low-light filming situations.
Optical performance follows cinema lens priorities — smooth rendering, minimal focus breathing, and consistent behaviour across apertures. Sharpness is good in the centre wide open with the expected softening at the extreme aperture. The wide-angle perspective combined with T1.2 creates interesting bokeh possibilities not usually available at this focal length on APS-C.
L-Mount for APS-C cameras. Filter thread is 67mm — matching all other Nightwalker lenses for consistency during production. Weight is approximately 530 grams. Build quality features a geared manual focus ring, de-clicked aperture iris, and cinema-standard barrel design. The lens is designed to match the colour science and rendering of other Nightwalker primes.
Available on the used market at moderate prices. Check for smooth geared ring operation. The matching filter size and consistent rendering across the Nightwalker set makes them practical for budget indie productions. Not designed for stills photography — video creators on APS-C L-Mount systems are the target audience.
