Yeah, it models physical lenses exactly, so it matters. This is an anamorphic virtual lens. You can tell by the vertical oval shaped lens flares. They tend to increase the sense of scale in a subtle way. The unique aesthetic created by the native distortion and compensation within the lens produces a familliar cinematic aesthetic that can't be achieved with standard lenses. Once you learn to spot them, you'll be surprised how many films were made with them. In example "The Batman" and "Avengers Endgame", plus all of Tarentino's stuff, and about a million others.
They are harder to focus pull, but once you start to master the technique, you can get a lot of cool effects out of them.
