Smartphones have had other optical zooming options in the past, the most popular solution being the one employed by the iPhone 7 Plus: having two sensors, one of which is permanently zoomed in, and using software to seamlessly combine the two. Oppo’s 5x, however, does things a bit differently, since the second sensor is hidden inside the phone’s chassis at a 90-degree angle.
Apple's iPhone 7 Plus only has 2x optical zoom
The tech works with a telephoto lens, which is rotated perpendicularly inside the device, and the light from which is then reflected through a rotating prism. The mechanism can rotate by increments of 0.0025 degrees, allowing for precise control of zooming, and also includes picture stabilization. Oppo claims the result is “lossless” 5x zooming, though we still have to see it in action before we believe it.source: Oppo
