MWC 2017: Oppo Demonstrates 5X Optical Zoom for Smartphones
 

This year at MWC, Oppo showed off a smartphone prototype that used a new implementation of dual cameras to offer a 5X optical zoom. The company did not reveal anything about the actual plans to use it for products, nor did they reveal the cost of its implementation, but it is likely that it will reach the market sometimes in the future.
