UPDATE: More iPhone 13 Pro cases have leaked alongside alleged iPhone 13 cases. The updated story continues below.
iPhone 13 Pro vs iPhone 12 Pro
An image shared on UnclePanPan’s Weibo account (via DuanRui) shows the smaller iPhone 12 Pro wearing what’s claimed to be a silicone case designed specifically for the upcoming iPhone 13 Pro.The case in question seems to fit the current-gen flagship perfectly, though the rear camera cutout is significantly larger. If the dimensions are accurate, the camera bump will occupy more than half of the iPhone 13 Pro’s rear panel on the horizontal axis.
One big reason for the larger iPhone 13 Pro cameras should be the introduction of sensor-shift stabilization technology, something that was reserved for the iPhone 12 Pro Max last year and is likely to bring stabilization to all cameras on the iPhone 13 line.

Apple is planning similar camera sensor upgrades for the iPhone 13 Pro Max and alleged cases suggest its bump will also be getting bigger, although the planned changes are rather minimal.
Sensor-shift stabilization is the main reason for the bigger bump on the smaller iPhone 13 Pro. But it was already present on the iPhone 12 Pro Max, so the size of the individual sensors is the main thing impacting the iPhone 13 Pro Max bump.

The switch to a diagonal setup means that Apple can fit noticeably bigger components into a bump that’s not much bigger than before.
