2017 could jolly well be the year where the dual-lens rear camera systems will begin to be more and more common on flagship models from various manufacturers. After all, there has been speculation in the past that the second camera lens on the back of the iPhone 7 Plus will function as an optical zoom, but until the real deal or additional information is shared by Apple themselves, we will just have to take such speculations with a pinch of salt.
However, we should take into consideration that Apple has a history of introducing premium features into its iPhone Plus models’ back camera, such as Optical Imaging Stabilization. All in all, it would be interesting to see just how much better image quality would get with the implementation of Sony’s dual-lens cameras across the board in due time.
