What is the resolution of the best lens?

The optimal lens resolution varies depending on the application scenario:
The standard for measuring lens resolution
Lens resolution refers to the ability of a lens to distinguish details, usually expressed in line pairs per millimeter (LP/mm), with higher values resulting in clearer images. The resolution of professional fixed focus lenses can reach over 120 lp/mm, while in daily use, a 1080P (1920 × 1080) driving recorder resolution can meet most needs.  ‌
The optimal resolution for different scenarios
Professional photography: requires high-resolution lenses, such as 4K resolution (3840 × 2160) to achieve finer detail capture.  ‌
Driving record: It is recommended to use 1080P (1920 × 1080) for daily use to balance image clarity and storage requirements; If higher details are required (such as license plate recognition), a 2K resolution (1440P, 2560 × 1440) can be considered.  ‌
Balancing storage and performance: High resolution will significantly increase storage requirements (such as reducing recording time from 200 minutes to 100 minutes on a 16GB memory card), and the choice should be based on storage capacity and device performance.  ‌
