Oppo has taken the biggest challenge of smartphone cameras, which is their inability to provide optical zoom while keeping the device to a slim profile, and thought sideways about it. The new system has one traditional camera sensor and one that’s been pivoted 90 degrees so that it doesn’t face the back of the phone but looks to the side instead. Then there’s a series of lenses to focus the light onto that sensor, which arrives into the phone and is pointed at the sensor via a mirror, or prism. Basically, it works just like a periscope.

The periscopic zoom system
The diagram of Oppo allows us to see more clearly. If the wide-angle module faces the subject, the telephoto module is perpendicular, but a clever prism system allows the light to reach the sensor as a periscope. This saves space in thickness. Oppo announces the possibility of zooming X5 hybrid without loss , relying on the optical stabilization of the telephoto module. The wide-angle module is not stabilized.
