OPPO is set to introduce 10x optical zoom technology on January 16, 2019 in Beijing, China according to a supposedly leak.
Prior to this, the company unveiled the world’s first dual camera with 5x optical zoom at MWC 2017. It was a 5P lens followed by a 90-degree angular prism that directs the light to a vertically positioned camera sensor. On the other end is the OIS unit for it to work even when the zoom is maxed out.
The invite that was supposedly leaked, despite being in Chinese, shows the number 10 stretched out. They have yet to feature the 5x zoom camera on a smartphone so the 10x may likely be on a prototype device.
