iPhone 8 and up is pretty good-ish. You can do 4K. The X and XRs are way better. But I always felt my dlsr shot better then the iPhone. Iv made several adult films w the iPhone (I shot about 40 porno films in my previous life) that were released with big companies. It’s not unheard of.

There a couple Hollywood films. That trans-hooker movie I think it was called Tangerine was shot in iPhone.

Make sure to covert your video from VFR to CFR for premier and you should be good.

Use a FilmC pro or something that gies you Manuel control over the cameras.

At the end of the day. It doesn’t matter what kind of camera you got. Just what you done it. Recording studios today have more technology the they did when the Beatles made music. Look what the Beatles did w crappy equipment. It’s all about the artist. And less about the “thing” you used to make the art.
