autofocus and stabilization issues with the new IPhone Pro?

Hello julia e,

This page can help out with adjusting the camera's focus on the device: Use iPhone camera tools to set up your shot

Adjust the camera’s focus and exposure

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:

1. Open Camera.

2. Tap the screen to show the automatic focus area and exposure setting.

3. Tap where you want to move the focus area.

4. Next to the focus area, drag  up or down to adjust the exposure.

To lock your manual focus and exposure settings for upcoming shots, touch and hold the focus area until you see AE/AF Lock; tap the screen to unlock settings.

On iPhone 11 and later, you can precisely set and lock the exposure for upcoming shots. Tap , 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 it seems that it's going out of focus when the device gets closer, you may find some details here that can help with the macro switching: Take macro photos and videos with your iPhone camera

Control automatic macro switching

You can control when the camera automatically switches to the Ultra Wide camera for capturing macro photos and videos.

1. Go to Settings  > Camera, then turn on Macro Control.

2. Open Camera, then get close to your subject.

3. When you get within macro distance of your subject,  appears on the screen.

4. Tap  to turn off automatic macro switching.

Tip: If the photo or video becomes blurry, you can back up or tap .5x to switch to the Ultra Wide camera.

Tap  to turn automatic macro switching back on.

Automatic macro switching is re-enabled the next time you use Camera within macro distance. If you want to maintain your Macro Control setting between camera sessions, go to Settings > Camera > Preserve Settings and turn on Macro Control.

Cheers.
