The front camera of four new iPhone 14 models in 2H22 would likely upgrade to AF (autofocus) & about f/1.9 aperture (vs. iPhone 13's FF (fixed-focus) and f/2.2).

AF support and a lower f-number can provide a better shallow depth-of-field effect for selfie/portrait mode. In addition, AF can also enhance the focus effect for FaceTime/video call/live streaming.
