How we researched
This review is based on SIRUI Night Walker T1.2 S35 Cine Lens's official product page, its published specifications and pricing, and a comparison with leading alternatives in tech & gadgets. We have not used this product ourselves; scores reflect how it compares on paper.What the Night Walker series is
The SIRUI Night Walker is a family of five cine prime lenses built for APS-C and Super 35 cameras. The lineup started with 24mm, 35mm and 55mm models, and SIRUI later added a 16mm wide angle and a 75mm short telephoto.
Every lens in the set shares a T1.2 maximum aperture. On an S35 sensor, SIRUI lists the full-frame equivalents as roughly 24mm, 34mm, 49mm, 77mm and 113mm, which covers wide establishing shots through tight portraits.
The lenses come in black or a vintage-style metal gray. You can buy them individually or as a 16mm plus 75mm set or a 24mm, 35mm and 55mm set.
Key features and optics
The headline is the T1.2 aperture. SIRUI says it lets you cut back on fill light and avoid very high ISO settings in dim scenes, and that images stay sharp wide open. Those are the brand's claims, so it is worth looking at independent sample footage before buying.
SIRUI says it uses aspherical elements, ED glass and high refractive index glass to keep the lenses compact while controlling aberrations, distortion and focus breathing. The 16mm uses 14 elements in 5 groups with 13 aperture blades, and the 75mm uses 13 elements in 4 groups with 18 blades. The 24mm, 35mm and 55mm each use 12 aperture blades.
The aperture ring is stepless, which matters for smooth exposure changes during a take. The focus ring has a 270-degree throw, giving finer control for manual focus pulls.
Build and handling
SIRUI says the lenses use an aluminum alloy body. Each lens shares a 79mm maximum diameter, a 77.6mm focus ring, a 67mm filter thread and identical gear positions, so a follow focus and matte box can stay in place when you swap lenses.
The catch is weight. The 24mm and 35mm come in around 505g to 518g, while the 16mm, 55mm and 75mm run roughly 555g to 601g depending on mount. That is heavy for crop-sensor lenses and worth checking against your gimbal's payload.
One note: the spec table lists the RF-mount 24mm at 809g, which conflicts with its own pound figure of 1.12 lbs. That looks like a typo, but confirm with SIRUI if exact weight matters to you.
Price and value
At the time of writing, a single 16mm lens in black with E-mount was listed at $319, down from $399, and that variant was backordered. Other listings for the series on the store start from $279. Prices vary by focal length, mount and set.
For a T1.2 cine prime with gearing and a long focus throw, that is low pricing. Dedicated cinema primes from traditional makers often cost many times more per lens.
Single lenses ship with a storage bag, while sets come in a package box. SIRUI offers free replacement within 3 years for non-human product defects.
Who it suits and who should skip it
This series makes the most sense for indie filmmakers, documentary shooters, and content creators using APS-C or Super 35 bodies who want a consistent look across several focal lengths without a large budget.
It is a poor fit if you shoot full frame, since these lenses cover only APS-C/S35. It is also not ideal for solo shooters who depend on autofocus or anyone building a very light run-and-gun rig.
MFT users should note that the focal length equivalents SIRUI lists are for S35 sensors. On a Micro Four Thirds body, each lens will frame tighter.

FAQ
Is the SIRUI Night Walker a full-frame lens?
No. SIRUI lists the coverage as APS-C/S35 for all five focal lengths. On a full-frame camera you would need to use a crop mode.
Does the SIRUI Night Walker have autofocus?
The page does not list autofocus. The lenses are built as cine primes with focus gears, a 270-degree focus throw and a stepless aperture ring, which point to manual focus use.
Which camera mounts does the Night Walker support?
The 24mm, 35mm and 55mm come in Sony E, Fuji X, Canon RF and MFT. The 16mm and 75mm add L-mount as well.
How much does a SIRUI Night Walker lens weigh?
SIRUI lists weights from about 505g to about 601g depending on focal length and mount. The 24mm and 35mm are the lightest, and the 75mm RF is the heaviest listed.
What is the warranty on SIRUI Night Walker lenses?
SIRUI states free replacement within 3 years for non-human product defects. Damage caused by the user is not covered under that wording.
Final verdict
For APS-C and Super 35 filmmakers, the SIRUI Night Walker series offers fast, matched cine primes at an accessible price, with practical touches like shared gear positions and filter threads. Its brand claims on sharpness and breathing should be checked against independent footage, and its weight and crop-only coverage rule it out for some shooters. If those limits fit your setup, it is a strong value pick.
