I have noticed the aperture button on the bottom left hand side of the camera app on the iPhone 17 Pro Max is missing? Like I can’t change the focus after taking a picture on the main photo screen but it works when I use the portrait option. I have a 16 pro max running the same version of IOS 26.0.1 and it works fine.
The streaming of the interface has changed things. In the upper left corner make sure HEIF 12 or 24 is selected. Photo is selected. Focus on an object 6 to 8 feet away. Too close and it won’t do it in Macro and too far and it won’t do it. Press and hold finger on subject. Camera goes into AE/AF lock and yellow box appears around subject. F/ should appear in lower left. If it doesn’t, double check it’s still 12 or 24 MP. Once I had it not appear and I checked and it showed 48 when I opened panel in upper left. I set back to 24 and f instantly appeared.
Just a reminder. It works in 1X, 2X and 4X but not 0.5X or 8X.

You must focus on something or have a face in the scene and the f/ will appear. Please see screenshot from my iPhone 17 PM. Also HEIF 12 MP or 24 MP must be used. Adjustment of DOF can also be done in Apple Photos app or third party apps like Focos.
I’ve done that and it still won’t work. I remember being able to change the focus on photos after taking them but not working on my 17 pro
