Is the sirui nightwalker lens worth buying?

The sirui nightwalker series lenses are suitable for users with limited budgets and the need for lightweight movie shots. Its maximum aperture reaches T1.2, providing high cost-effectiveness and unified design. However, there are issues such as insufficient image quality when the aperture is fully open and significant dispersion when the aperture is large.  ‌
Core advantages
Lightweight design: Each lens weighs about 500 grams and comes with a uniform 67mm filter size, making it suitable for long-term handheld shooting
Large aperture shooting: The maximum aperture of 24mm, 35mm, 55mm and other focal lengths reaches T1.2, and there is no need for supplementary lighting in low light environments
Multi port compatibility: Supports mainstream ports such as Sony E, Fuji X, Canon RF, etc., with strong expandability
Main shortcomings
Image quality limitation: Insufficient sharpness in focus when the aperture is fully open, and significant dispersion at large apertures. It is necessary to shrink the aperture (such as T2.8 or above) to improve
Focusing damping: The damping of the focusing ring and aperture ring is relatively small, and the operating feel is average. It is necessary to replace the lubricating oil for optimization
Applicable scenarios
Humanities/Street Photography: The 24mm wide-angle lens allows for close proximity to the subject, while the 50mm lens is suitable for close ups of people
Night scene shooting: T1.2 aperture can achieve clear shooting in low light environments, but attention should be paid to purple edges and dispersion issues
If you pay attention to lightweight shooting and cost-effectiveness, and can accept post production adjustment parameters, this lens group is a good choice; If pursuing the ultimate picture quality, it is recommended to consider other brands.
