iPhone 13 pro camera telephoto pictures show distortion and lines

Hi ajnch,

It certainly is odd. However, you'll want to ensure your iOS is fully updated. Update your iPhone, iPad, or iPod touch - Apple Support

If the issue continues, check out and complete the helpful steps here: If the camera or flash on your iPhone, iPad, or iPod touch isn't working - Apple Support

Specifically the quoted section below.

"If the camera isn't working

1. Remove any case, accessory, or film that might block the camera or that places a magnet near the camera.
2. Test the camera by trying to take a photo.
3. If the photo is blurry, clean the front and back camera lenses with a microfiber cloth. If you see dirt or debris inside the lens or if the camera lens appears to be misaligned or blocked, contact Apple Support for help with your iPhone, iPad, or iPod touch.
4. Restart your iPhone, iPad, or iPod touch. 
5. Test the camera again by taking a photo. If your device has a front and rear camera, check if one or both isn’t working. To switch cameras, tap the rotate button ."

If the issue remains, reach out to Apple Support directly to further assist.
