Oppo has announced the Find X7 Ultra, a new flagship phone that sports two periscope cameras; that's a world first. 

While periscope cameras are now fairly common in some of the best phones, having a pair of them in a single rear-camera array is new, due to the components and lens stacking needed to get them to work while keeping telephoto camera modules from protruding too far out of a phone's rear.
