Lens Overview — Sirui 35mm T1.2
Key Features — Sirui 35mm T1.2
T1.2 Maximum Aperture: A true T1.2 transmission rating — rather than an optical f-stop — delivers accurate, consistent exposure in low-light conditions, particularly useful for video work.
T-Stop Calibrated Rating: T-stop values measure actual light transmission through the lens, making exposure matching more reliable when cutting between multiple lenses in a video project.
35mm APS-C Prime: A fixed 35mm focal length on APS-C sensors yields a standard field of view well suited to street, documentary, and everyday shooting.
Manual Focus Design: A dedicated manual focus ring gives shooters direct, tactile control over focus — a workflow preferred by videographers and deliberate still photographers.
Four Mount Options: Available in Sony E, Canon RF, Nikon Z, and Fujifilm X mounts, covering a broad range of popular APS-C mirrorless systems.
67mm Filter Thread: A widely supported filter diameter that is compatible with common protective, ND, and creative filter systems.

Description — Sirui 35mm T1.2
The Sirui Night Walker 35mm T1.2 is a manual focus prime lens designed specifically for APS-C mirrorless camera systems. Its standout specification is the T1.2 maximum aperture, a cinematically calibrated T-stop rating that ensures accurate and consistent light transmission — particularly valuable for video shooters who need reliable exposure matching across a lens set. The fixed 35mm focal length places it in the standard range for APS-C cameras, offering a natural perspective well-suited to street, documentary, and everyday photography.
With no autofocus and no image stabilization, this lens rewards a more deliberate, controlled shooting approach. The 67mm filter thread provides broad compatibility with standard filter accessories. Weighing 700g, the Night Walker has a solid, confident build.
It is offered across four mount options — Sony E, Canon RF, Nikon Z, and Fujifilm X — making it accessible to shooters across the major mirrorless platforms without the need for adapters.
