Looks pretty nifty, though it’s interesting that it doesn’t (at least currently) work for capturing video or macro shots:

The Verge explains,

The key component to Oppo’s system is a periscope setup inside the phone: light comes in through one lens, gets reflected by a mirror into an array of additional lenses, and then arrives at the image sensor, which sits perpendicular to the body of the phone. That’s responsible for the telephoto lens in Oppo’s array, which has a 35mm equivalence of 160mm. Between that lens, a regular wide-angle lens, and a superwide-angle that’s 16mm-equivalent, you get the full 10x range that Oppo promises.
