I didn’t notice until later i bought my phone that whenever i use portrait or zoom in my camera to 2.5x upwards it doesn’t focus on anything and all remains blur the i tried with a friend phone (also a 12 pro max and there was a huge difference)
iPhone 12 Pro Max, iOS 16
If you are using a third-party camera app then please use the iOS Camera app and then compare.
Use iPhone camera tools to set up your shot
Before you take a photo, the iPhone camera automatically sets the focus and exposure, and face detection balances the exposure across many faces. If you want to manually adjust the focus and exposure, do the following:
up or down to adjust the exposure.
, tap 
, then move the slider to adjust the exposure. The exposure locks until the next time you open Camera. To save the exposure control so it’s not reset when you open Camera, go to Settings 
> Camera > Preserve Settings, then turn on Exposure Adjustment.If you are using a third-party camera app then please use the iOS Camera app and then compare.

I am not using a third party camera. Even when i used snapchat to zoom in it was clear and it had good focus. On the iOS camera i used video mode to zoom in and it wasn’t blurry. Only when i want to take a photo or portrait it gets blurry. I tried the exposure settings you talked about. Didn’t work
Had to have my camera assembly replaced
at Apple Store. Did a complete restore to factory defaults before I did this. Still convinced it was the iOS update but I was leaving on vacation and needed the camera to work. It was $200 To fix.
Any success to fix this issue? I have the same problem. Thank you.
Did you get this resolved? I have the same issue.
I do too. Mine was working before I upgraded to iOS 17
I replaced the camera assembly. Apple Store completed it in about an hour.
Ditto. Upgrading OS broke zoom focus.
Are you saying you did a factory reset before worked?
The factory reset did not work.
So how did you get it fixed
Brought it to apple store. Fixed it in an hour. Make an appointment.
Thanks. Did they explain what was wrong? My situation is the same as the OP’s. Appears to be a software problem as zooming works fine on apps that uses the camera like Snapchat
No explanation. I gave up and just replaced the camera lens components. Needed it for vacation. But I firmly believe it was software related.
