A new image shared by UnclePanPan on Weibo and shared on Twitter by DuanRui shows a case of the new iPhone 13. There’s an iPhone 12 model in the case which indicates that the iPhone 13 will have a larger camera module.
It has previously been rumored that Apple will upgrade the camera modules of the new iPhones by adding Pro like features and Sensor Shift Stabilization on all models. This means the camera module should be larger than the one on the iPhone 12 models.
Case manufacturers might also be basing their case designs based on leaks and rumors so it’s not clear if the iPhone 13 will have a significantly larger camera module.
