iPhone 12 Pro Max Portrait photos look like mess on 1x zoom

[primekazan]

Recently I've got mine 12 Pro Max and was testing some camera capabilities. Photos were taken at night with low light but they look like a total mess when trying to make a portrait mode on 1x. 2.5x is looking perfect. Example photos below. I was testing this with some better light (also indoors) and with more complex objects but it gets even worse than that - the photo is blurred randomly with some spots leaved unblurred and some blurred (the photo with chair).
Anyone have similar issue?

I don't think portrait mode is designed for those subjects.

Yeah, yet it still does the same with people on photos. I used chair as an example of what is happening.

Are you saying it blurs the background when not taking portraits?

On portrait mode on 1x zoom with interior light (wasn’t checking yet if the issue occurs outside with good light) it is blurring without logic - the backround i blurred partially alongside with front object being blurred as well in some spots. There is no pattern to it. Looks like camera or lidar does not recognize what is in front and what in back of the photo.

This is an issue Portrait Mode has had for years.

Small objects get blurred out or disappear altogether - ears get blurred, hair goes weird looking as there's no specific hard focus point. Its the difference between a true portrait effect using an optical lens with manual focus vs a digital effect overlaid on a photo using a couple of lenses.
