Apple is expected to launch four iPhone 13 models this year, bearing the same display sizes as their direct successors, the iPhone 12 series. Where the iPhone 12 Pro Max was the only member to be treated to Sensor-Shift Optical Image Stabilization, there are reports claiming that all four models will feature this upgrade. However, it appears that the more premium iPhone 13 Pro and iPhone 13 Pro Max may get the same stabilization tech for two different camera units, assuming the latest report turns out to be correct.

According to DigiTimes, the iPhone 13 Pro and iPhone 13 Pro Max will get Sensor-Shift upgrades for both wide and ultrawide cameras, leading to improved stabilization when capturing still images or video. These news lenses will also feature autofocus upgrades, though the nature of these upgrades was not included in the report.
