Yes—one useful option mentioned is The-Digital-Picture’s Lens Image Quality tool, which lets you compare test-chart results from two lenses side by side, often across different apertures and focal lengths. That’s probably the closest match to what you want.

A Nikon lens simulator was also mentioned, but that is more about comparing field of view/zoom range than true optical image quality.

That said, there’s an important limitation: lens comparisons are hard to make perfectly fair. Different copies of the same lens can vary, and some comparison sites test lenses on different camera bodies, which can affect results. So treat side-by-side tools as guides, not absolute truth.

For cheap or mid-range modern lenses, real-world differences are often smaller than people expect. Unless you’re comparing lenses with very different features or focal lengths, most current lenses will perform well if used in good light and without extreme contrast or bright light sources in the frame.
