Great test comparison from Andrew Hoyle:
To find out if it can hold its own as a professional video tool, I challenged our sister brand, Carfection, to produce a video shot entirely on the iPhone 11 Pro.
Carfection’s Charlie Rose:
I’m a bit divided over the footage. In great lighting, like the daylight we had for much of the morning, it looked amazing. You wouldn’t be able to tell that it was shot on an iPhone.
You also don’t get the same depth of field you’d be able to achieve with a big image sensor. That’s a big giveaway that what you’re looking at is shot on an iPhone. It’s difficult to get that cinematic look.
That’s my take, too. It’s hard to beat the physics of a big lens and sensor.
