While the iPhone currently maxes out at 3x optical zoom, rumors suggest that will change this year. The next-generation iPhone 15 Pro Max is widely expected to feature a so-called “periscope lens” that would allow for up to double the optical zoom.

In July 2022, Apple analyst Ming-Chi Kuo said a periscope lens would be exclusive to the high-end iPhone 15 Pro Max and enable 5-6x optical zoom. Periscope technology would be built into the Telephoto lens and allow for up to 6x zoom when shooting photos with the rear camera, without any blurriness or reduction in image quality.

With a periscope lens, light absorbed by the image sensor is bent or “folded,” allowing for a greater distance between the camera elements within the compact design of a smartphone.
