On November 5, it was reported that Xiaomi released its self-developed "Telescopic Large Aperture Lens Technology" at today's MIDC 2020 Xiaomi Developer Conference. As the name implies, it is to add a retractable lens similar to a card camera to the mobile phone to achieve the effect of multi focal section photography, which is expected to end the coexistence of multi camera in mobile phones.

Zeng Xuezhong, president of Xiaomi Mobile Phone Department, claimed that the "telescopic large aperture lens technology" has a large aperture, which can increase the light input by 300%, and has a new anti shake technology, which can make the picture more stable and improve the definition by 20%.

In the demonstration video, the demo machine used seems to be based on Xiaomi 10, with a familiar hyperbolic screen on the front and a shell similar to 3D printing on the back. It can be seen that the camera bulge of the demonstration machine is not very serious, which is slightly normal than the well-known Nokia Lumia 1020.

The telescopic lens can be moved in two sections like a card machine. The middle section is made of metal and can be stretched out during shooting. The durability is unknown, but this structure has been used in the camera industry for decades, so it should not be a problem. But with such a large mechanical structure, dust-proof and waterproof products like IP67 and IP68 seem hopeless.

The demonstration machine of telescopic large aperture lens technology looks like us Love to play computer games The appearance patent of Xiaomi was reported in July, but the focus at that time was the back auxiliary screen. In order to achieve multi focus segments within 1cm of the mobile phone body, multiple cameras and even periscope telephoto lenses are introduced. The telescopic camera can end the long focus multi shot line in one breath and complete the unification. And if you can use the contemporary main camera as the zoom, the image quality should be better than that of the ultra long focus with IMX586+5 times light on Xiaomi 10 Ultra.

Of course, if its focus segment can cover the ultra wide angle, the ultra wide angle lens can also be laid off. However, the aperture of the telescopic lens is generally small, which makes it difficult to reach the normal F1.8-F1.9 level of mobile phones. It is still unknown what level of aperture can be achieved by Xiaomi's "telescopic large aperture lens technology".
